Introduction 1
Spitfire Basics
Benefits of an On-Board Effect Processor
If you use guitar effects, you probably do so by linking
pedals together into a chain or by using a multi-effect
processor. All this extra equipment can cost a fortune
and crowd your playing space. The Spitfire, however,
simplifies things because it includes all the effects you
need right in your amplifier. Instead of tripping over
extra wires and turning knobs and pushing buttons on
pedal after pedal, with the Spitfire you have full control
over dozens of effects without the need for an external
processor!
Effect Modules
If you were to think of the Spitfire’s effect processor as
a series of individual pedals linked together, then each
pedal in that series would be considered an effect
module. The Spitfire has nine separate effect modules,
as shown below:
You can assign one effect to each of these modules and
adjust its parameters accordingly. For more on the
Spitfire’s effect modules, see chapter 10.
Effect Types
When we use the word “effect” in this manual, we’re
usually referring to an effect type. Each module provides
you with a selection of effect types, only one of which
may be chosen for each module. For example, the DIST
module allows you to select which type of distortion you
want (ACOUSTIC, TUBE CLEAN, RHYTHM and
others). The behavior of each of these effect types may
be adjusted in one or more ways to produce variations
of the effect.
5
1 Introduction
Parameters
A parameter is a control that changes the characteristics
of an effect. When we use the word “parameter,” we are
referring to the “direct control” parameter available to
the DIST, FX1, FX2 and FX3 modules. DIST’s
parameter is called DRIVE, and the parameters for FX1,
FX2 and FX3 are labeled PARAM. The characteristic
controlled by a parameter varies from effect to effect.
Programs
A program is a combination of effect
modules and their respective settings.
In PLAY mode, you have quick access
to the Spitfire’s eighty programs via the
Program Up and Down buttons, optional
footswitches and the VALUE knob. The
programs are divided up into banks A – H and are
identified by a bank letter and a program number on the
display.
Playing in Stereo
The Spitfire outdoes most other guitar amplifiers by
providing stereo output instead of the standard mono.
We strongly encourage you to take advantage of the
wonderful benefit this provides for your sound, because
many of the Spitfire’s excellent effects will sound even
better when you listen to them in stereo. See chapter 9
for instructions on how to connect a second amplifier to
the Spitfire using the STEREO LINK OUTPUT. If you
don’t have a second amplifier, you can immediately
enjoy the stereo effects simply by listening with
headphones.

Introduction 1
How to Use This Manual
This manual is divided into the following sections
describing the various functions and applications for the
Spitfire. While it's a good idea to read through the entire
manual once carefully, if you already have general
knowledge about guitar amplifiers and effects, you
should use the table of contents to look up specific
functions.
Helpful tips and advice
are highlighted in a
shaded box like this.
Chapter 2: Hookup Diagram shows you how to get the
Spitfire connected and turned on.
Chapter 3: A Tour of the Spitfire describes all the controls
and features of the unit. This chapter features labeled
diagrams of the front and rear panels. The paragraphs
that follow the diagrams provide more in-depth
explanations of these features.
When something
important appears in
the manual, an
exclamation mark (like
the one shown at left)
will appear with some
explanatory text. This
symbol indicates that
this information is vital
when operating the
Spitfire.
Chapters 4 through 9 include step-by-step instructions for
using the Spitfire, including how to select and edit
programs, use the tuner function, store and copy
programs, use the Defer Program Changes feature, and
stereo-link two amplifiers.
Chapter 10: Effects Knob Settings explains the Spitfire’s
effect modules and types, as well as other settings
controlled by the EFFECT and VALUE knobs.
Chapter 11: Troubleshooting can give you a hand if you’re
experiencing problems with the Spitfire. You’ll find that
most issues can be resolved simply and quickly.
Chapter 12: Specifications is full of information for the
more technical users.
Chapter 13: Contact Information lets you know the best way
to reach us if you have any questions or comments.

2 Hookup Diagram
The first thing we’ll show you is how to get your Spitfire
up and running. The following diagram shows you the
most common method of hooking up your Spitfire, but
you certainly aren’t limited to the devices you see here.
For example, you may want to connect a tape player to
the AUX inputs instead of a CD player. And you can
even use the Spitfire to amplify keyboards or other
instruments.
Although you can
experiment with
different types of
instruments, the Spitfire
performs best with a
guitar, as it was made
specifically to handle
that instrument’s
frequency range.

3 A Tour of the Spitfire
Input
Plug in your guitar here using a guitar patch cord. You
can also plug in another amplifier’s line output in order to
create a stereo link with that amplifier (refer to chapter 9 for
details). You should use a 1/4” tip-sleeve (TS) cable.
Make sure the amplifier
is turned off before you
connect your guitar or
any other instrument to
the Spitfire.
Program Up/Down
While in PLAY mode, the Program Up button
increments the program number, and the Program
Down button decrements the program number. When
you press both buttons together, the Spitfire goes into
BYPASS mode, in which the audio signal from your
guitar simply passes through the Spitfire without being
affected. When you hold both buttons down for longer
than half a second, the Spitfire goes into MUTE mode,
in which no signal at all leaves the amplifier. When you
are in BYPASS or MUTE mode, the tuner is activated.
Footswitches must be
plugged in and not
pressed when you turn
on the Spitfire.
Otherwise, the switches
may not function
properly.
You may use optional footswitches to perform the same
functions as the Program Up and Down buttons. The
Spitfire works with both normally open (NO) and
normally closed (NC) footswitches.
Display
This LED display is made up of two digits and two
decimal points. In PLAY mode the digits indicate the
current bank letter and program number. When you
turn the EFFECT knob to a module or parameter, the
two digits display the setting of the selection.
Descriptions of settings for each mode and parameter
are in chapter 10.
The Display also contains two decimal points, each to
the right of one of the digits. The # decimal point is
used by the Spitfire’s tuner to help indicate the pitch of a
note you’re playing, and the EDITED decimal point
lights up when you have changed the settings of the
current program. You can read more about these in
chapter 5 “Editing Programs” and chapter 7, “Using the
Tuner.”
12
A Tour of the Spitfire 3
EFFECT Knob
The EFFECT knob is used for selecting effect modules,
parameters and other settings to edit. Around the knob,
you’ll see the names of sixteen different settings,
including nine effect modules, four effect parameters
(DRIVE and the three PARAMs) and two program-
level settings (LEVEL and ROUTE). The PLAY setting
is what you’ll want to be in while playing your guitar
through the Spitfire.
Refer to chapter 10 for descriptions of the possible
values for the effect modules and parameters.
VALUE Knob
In PLAY mode, this knob lets you select a program.
When you make a selection other than PLAY with the
EFFECT knob, you are in edit mode, and the VALUE
knob allows you to change the setting of the mode,
parameter or global setting you have selected. Also, you
can press this knob to store changes you have made to a
program.
DRIVE Knob (Spitfire 60 and 30 only)
This knob gives you direct control of the DRIVE value,
which is the parameter for the DIST module. Increasing
the DRIVE value boosts the level of distortion and
increases the loudness of the audio signal.
If you turn the DRIVE
knob when the DIST
module is turned off, the
display will show “--”
and the audio signal
will not be affected.
When an effect program is recalled, the DRIVE value is
also recalled from that program regardless of the
position of the DRIVE knob. But once you turn the
DRIVE knob, the program will jump to the new
DRIVE setting, and the program will be edited, which is
evidenced by a lit EDITED decimal point on the display.
When you turn the DRIVE knob, the DRIVE value will
appear on the display for a few seconds. You may also
modify the DRIVE setting by turning the EFFECT
knob to DRIVE and using the VALUE knob to change
the amount of drive.
13
3 A Tour of the Spitfire
BASS Knob (Spitfire 60 only)
This knob gives you the ability to equalize (EQ) the low
frequencies present in your guitar’s audio signal. This
setting is not related to the EQ module found on the
EFFECT knob. Rather, it provides an additional means
of controlling the bass frequencies.
A program’s BASS and
TREBLE values will be
lost if you switch
programs without
saving that program
first. Be sure to save
your programs!
When you turn the BASS knob, the amount of bass in
the current program will increase or decrease
accordingly, the EDITED light will turn on, and the
display will briefly show the BASS setting. When you
save a program, the current BASS value is saved with it
so that it can be recalled later.
TREBLE Knob (Spitfire 60 only)
This knob works the same way as the BASS knob,
except that it controls the high frequencies of the audio
signal.
You should turn the
master volume all the
way down before you
turn on the amplifier.
This will prevent any
sudden pops that could
damage the speaker.
MASTER VOLUME Knob
The MASTER VOLUME knob controls the overall
volume of the audio signal that is output to the speaker,
the HEADPHONES jack and the STEREO LINK
OUTPUT on the rear panel. This value is not stored
with a program.
Also, make sure the
Power Switch is set to
OFF before you
connect your guitar or
any other instrument to
the Spitfire.
HEADPHONES Jack
Plug your headphones into this jack using a standard
1/4” stereo phone plug. If your headphones are 1/8”,
you can find a 1/8” to 1/4” adapter in most electronics
stores. The internal speaker, STEREO LINK OUTPUT
and SPEAKER OUTPUT are automatically disabled
when you are using headphones.
To get a real-life miked-
amplifier sound in your
headphones, check out
the effect processor’s
cabinet simulator
effects (page 32).
Power Switch
Use this switch to turn the Spitfire on and off.

Rear Panel
All three Spitfire models offer the rear-panel features
described here:
Fuse FOOTSWITCH UP/DOWN INPUTS AUX INPUT
SPEAKER OUTPUT
Power Cord EXPRESSION PEDAL INPUT STEREO LINK OUTPUT
Fuse
CAUTION: Danger of
fire or electrocution
exists if the fuse is
The fuse protects the Spitfire from damage caused by a
defective AC outlet. If this fuse blows, you must replace it.
incorrectly replaced.
Replace it only with the
same or equivalent type
of fuse recommended by
the information found
next to the fuse.
Power Cord
Plug the power cord into an AC outlet. The AC voltage
required is fixed at a single voltage based on the country
in which you purchased your Spitfire. The voltage is not
switchable (i.e., 110/220) or universal (i.e., 90-240). Be
sure to connect it to the proper voltage as indicated in
the information found on the rear panel.
We recommend that you
purchase footswitches
to use with your
Spitfire. They aren’t
very expensive, and
they greatly streamline
your interaction with
the amplifier,
FOOTSWITCH UP/DOWN Inputs
Here you can plug in standard footswitches to use for
incrementing and decrementing program numbers. The
foot switches work in the same way as the Program Up
and Program Down buttons. These jacks accept 1/4”
plugs.
particularly when
playing live.
EXPRESSION PEDAL INPUT
This input is for an optional expression pedal, which
gives you the ability to control effect parameters with
your foot. All effects listed in chapter 10 that have
“Pedal” in their names provide this capability. See
chapter 10 for a complete list of parameters. This jack
15
3 A Tour of the Spitfire
accepts a 1/4” plug. Expression pedals may be
purchased at your local Alesis dealer.
AUX (Auxiliary) INPUT
The AUX INPUT allows you to play along with your
favorite songs! Just connect this RCA input to the
output from your CD player, tape player or some other
external audio device. The AUX INPUT level is fixed,
but you can use the external audio device’s own volume
control (for example, the headphone volume control on
a portable CD player) to adjust the level of the signal
coming into these jacks. When you turn the MASTER
VOLUME knob, the level of this signal is affected as
well.
STEREO LINK OUTPUT
See chapter 9 for
detailed instructions on
how to set up a stereo
link between two
amplifiers.
To take full advantage of the on-board stereo effect
processor, connect the STEREO LINK OUTPUT to
the input of a second amplifier to create a true stereo
setup. This jack accepts 1/4” TS cables.
SPEAKER OUTPUT
You can use the SPEAKER OUTPUT to connect the
Spitfire to an external 8-ohm speaker with a 1/4” TS
cable. This will disconnect the internal speaker.
The SPEAKER
OUTPUT is high-
voltage and can easily
damage normal
recording, PA, and
other line-level input
stages, so do not
connect this output to a
recording device, a PA
system, or the input of
another Spitfire.
Connect it only to an 8-
ohm speaker.

4 Selecting Programs
After you’ve plugged everything in, you’ll probably want
to check out the factory presets we programmed into
the Spitfire. This chapter shows you how to do that.
To Select Programs
1.
2.
3.
Make sure the Spitfire is hooked up properly and
turned on, as outlined in chapter 2.
Make sure you’re in PLAY mode (turn the

programs.
Footswitches (not provided with the Spitfire)
This is the easiest way to switch programs,
especially while playing your guitar. Just plug
footswitches into the FOOTSWITCH UP and
DOWN inputs and step on them to increment
and decrement the program number. You can
hold down a footswitch to increment or
decrement programs continuously.

program and then follow the steps outlined above to
store it to a new location.
21
6 Storing & Copying Programs
Arranging Programs for Performance
You can use the copy function to arrange programs
logically for easy recall during a performance. Take a
typical song structure for example (intro, verse, refrain,
etc.). For each part of the song, you may want to use a
different effect program. To ensure uninterrupted
performance, you can copy the programs used in the
song into an order similar to the following example:
Program Number
Song Section
Introduction
Verse
A0
A1
A2
A3
A4
A5
Refrain
Verse
Bridge
Refrain
With an arrangement like this, you can just press the
Program Up button or footswitch once to progress to
each section of your song. Using the 80 available
program locations, you can even arrange the programs
conveniently for multiple songs in a set. For example,
you can use programs A0-A5 for the first song,
programs A6-B0 for the second song, and so on.
Another convenient way to switch programs during a
performance is to enter deferred program-change mode,
which is explained in chapter 8.
22
7 Using the Tuner
To Tune Your Guitar
1.
In Play mode, enter BYPASS
or MUTE
mode by pressing the Program Up and Down
buttons at the same time once (for BYPASS) or by
holding them both down for more than half a
second (for MUTE). The display will now show
tuning information.
2.
3.
Make sure your guitar is connected to the Spitfire,
and play the open string you wish to tune. The left
digit of the display indicates the pitch nearest that
of the open string. If the # decimal point is lit, the
note is a sharp. If it is not lit, the note is a natural.
Remember, the optional
footswitches work the
same way as the
Program Up and Down
buttons. Step on both
footswitches once to
enter BYPASS mode,
and hold them down for
more than half a second
to enter MUTE mode.
Look at the right digit of the display to determine
if the pitch is correct. If the top four segments of
the digit are rotating clockwise, then the pitch is
higher than the pitch shown in the first digit. If
the bottom four segments are rotating
counterclockwise, the pitch is low. The more the
pitch is off, the faster the rotation. If no pitch is
detected, you’ll see a dash in the left digit.
4.
Tune the string until an 8 appears in the second
digit, indicating that the string is in tune with the
pitch displayed in the left digit.
The visual guide on the next page shows what
you’ll see on the display while tuning your guitar.
23
7 Using the Tuner
Visual Guide to Tuning
Here are the 12 possible
pitches (a decimal point
indicates a sharp):
Low
High
In tune
The bottom four segments rotate counterclockwise
if pitch is low. The top four rotate clockwise if the pitch
is high. An 8 means the string you have played is in tune
with the displayed pitch.
= no pitch detected.
Changing Pitch Reference
If you turn the VALUE knob while using the tuner, the
display shows you the setting for the Spitfire’s pitch
While you are viewing
or editing the pitch
reference, which is set to 440Hz (shown as
) for the
reference, the display
will return to pitch

this setting is 35 to 45, which represents 435Hz to
445Hz.
indication if you do not
rotate the knob for
more than two seconds.
When you turn the Spitfire on and off again, the
reference pitch is reset to 40.
24
8 Deferred Program Change
When you switch programs, the Spitfire normally
changes immediately to the program shown on the
display. However, in some situations—especially when
playing live—you may want the ability to scroll through
program numbers while remaining in the current
program setting. For example, let’s say you’re soloing in
a program that gives you strong distortion and fat
chorus. If you want to continue playing while you scroll
up to a program that provides a clean rhythm sound,
you’ll have to be in deferred program-change mode.
See “Arranging
Programs for
Performance” in
chapter 6 for an
alternative to deferred
program-change mode.
Enabling & Using Deferred Program Change
1.
As you turn on the Spitfire, hold down one or both
of the Program Up/Program Down buttons.
Letters will scroll by on the display, spelling the
word “deferred.”
2.
While in PLAY mode, use the Program Up or
Program Down button or the VALUE knob to
change the program number. The Spitfire will
remain in the program it was in before you
changed the program value. Also, the display will
flash the digit that is different from the currently
selected program. For example, if you are playing
in program D5 and scroll up to program D7, the 7
will flash. If you scroll up to F2, both digits will
flash.
You may also use the
optional footswitches to
change program
numbers.
3.
4.
Once the display shows the program number you
desire, press the Program Up and Down buttons
together or step on both footswitches to confirm
the program change. The display will stop flashing
and the Spitfire will switch to the new program.
Deferred program-
change mode is
especially useful when
you’re performing and
want to switch easily
between a rhythm
setting and a lead
setting as you continue
playing.
To return to normal program-change mode, turn
off the Spitfire and turn it back on without
holding down any buttons or footswitches.

9 Stereo-Linking Two Amplifiers
To take full advantage of the Spitfire’s stereo capability,
you can link it to another amplifier to create a true
stereo setup. This section explains how to do that.
To Stereo-Link Two Amplifiers
1.
Place the Spitfire and the auxiliary amplifier far
enough apart to allow for a decent stereo
spectrum. A few feet should be sufficient.
2.
3.
Make sure both amplifiers are turned off and that
your guitar is connected to the Spitfire.
Using a 1/4” TS cable, connect the
Spitfire’s STEREO LINK
Stereo Link
Output
Input
OUTPUT to the input of the
auxiliary amplifier.
4.
5.
Turn on the Spitfire
amplifier first, and then turn
on the auxiliary amplifier.
Spitfire
Auxiliary Amplifier
Play your guitar and adjust the
volumes of both amplifiers until they are
approximately equal. You may also want to adjust
the tone of the auxiliary amp so that it matches
the Spitfire’s tone as much as possible.
To see which effects are
in stereo, refer to the
descriptions in chapter
10.
6.
Now you’re playing in stereo! Experiment with the
Spitfire’s stereo effects to hear what a great
difference two amplifiers can make. The best
listening spot is a position that is between the
amplifiers and equidistant from each, with both
amplifiers facing you.

In this setting the display shows you the current program number. This is the
mode in which you should be performing, as it allows you to easily switch
programs via the foot pedals.
Indicates the bank letter and program number of the current
program.
COMP/LIMIT (Compressor/Limiter)
Compression evens out the high and low volumes of your sound by squeezing
them into a thinner range of levels, bringing down the high levels and boosting
the low ones. Limiting controls only the high levels.
Provide increasing levels of compression.
Provide increasing limiting.
Off
Turns COMP/LIMIT off.

Tube Clean
Simulates the clean sound of a classic tube amplifier.
Rhythm
A slightly distorted sound; great for rhythm playing.
Overdrive
Provides more grit than the Rhythm setting, like you’re really
pushing those amplifier tubes.
Distortion
Adds crunchiness to your sound.
Blues
A warm yet slightly crunchy sound associated with some of the
blues-guitar greats.
Fuzz
That classic fuzz distortion effect of the 60s. Just listen and you’ll

EQ (Equalizer)
This setting gives you a 4-band equalizer that you can use to shape the sound of
your audio signal by cutting and boosting certain frequencies.
Varying levels of cut and boost for low, middle and high audio
frequencies broken down as follows:
01 – 10: attenuated highs and emphasized lows
11 – 20: less attenuation of highs and emphasis of lows
21 – 24: emphasized midrange
25: Flat EQ curve
26 – 30: emphasized highs
31 – 40: attenuated lows and emphasized highs
41 – 50: emphasized presence and lows
Off
Turns off the EQ.
NR (Noise Reduction)
This is a combination of two effects—hum elimination and noise reduction.
Hum elimination works by cutting out the frequency that contains the hum
(60Hz). Noise reduction works by gating the signal (muting the signal until its
level rises above a certain point).
Hum Elimination (Left digit of display)
Increasing levels of hum elimination (60Hz harmonic notch filters).
Turns off hum elimination.
31
10 EFFECT Knob Settings

aggressively for more effect. Higher values indicate higher input
sensitivity.
Pedal-Controlled Wah
A wah sound controlled by moving the optional expression pedal
up and down as you play.
Phaser
An effect that shifts the phase of the signal and adds it to the
original sound (in simpler terms, it adds a duplicate signal that is
delayed a bit). The phaser gives your guitar a full, pulsating sound.
Higher values result in more feedback, producing a more intense
effect.
32
EFFECT Knob Settings 10

EFFECT Knob Settings 10
PARAM (Direct-Control Parameter for FX1)
This parameter modifies the operation of the effect selected for the FX1
module. Changing between effect types with dissimilar value ranges will scale
this value accordingly. For example, if you set Phaser to PARAM=63 and then
switch to the Auto Wah effect, its PARAM value will be 12. Changing back to
Phaser will result in a PARAM value of 63.
Indicates the value of FX1’s direct-control parameter, according to
the following:
For Auto Wah, Phaser, Tremolo, Step Filter, Auto Pan, Flanger
and Chorus, indicates the rate of the effect.
For Ring Mod, indicates the rate of the modulation.
For Slow Attack, indicates the rate of the attack.
For Rotary Speaker, indicates the rate of the speaker rotation.
For Pedal Pitch Transpose Up and Down, indicates the amount of
pitch change in 1/4 semitones (from 1/4 semitone to more than 2
octaves). Wet/dry mix is fixed at 100% wet.
For Cry, indicates the sensitivity of the filter modulation.
For Pitch Transpose with a fixed interval, denotes the wet/dry mix
from 0 (100% dry) to 10 (50% wet, 50% dry) to 20 (100% wet).
Indicates that the expression pedal controls the parameter.
Indicates that the effect assigned to the FX1 module does not have
a direct-control parameter (like Pedal Wah) or that FX1 is off.
FX2 (Multi-Effect Module 2, Stereo Effects)
This module gives you a choice of stereo effects. These effects include all those
found in FX1 except for Flanger, Rotary Speaker, Chorus and Pitch Transpose.

ROUTE
In this position, the display indicates the current signal-routing order of the FX
modules. This ordering can have a big effect on your sound, as each effect in the
configuration feeds into the next. Whatever the configuration, the LEVEL
setting always comes last in line.
This is the default order.
This one is the default order with FX2 and FX3 swapped to put
the delay effects in the middle of the modulation effects.
This order places the cabinet simulator at the end, allowing it to
emulate multiple effects pedals feeding into a cabinet.
This one is order 2 with FX2 and FX3 swapped.
This order is the default order with the compressor/limiter placed
at the end, making this one ideal for recording.
This one is order 4 with FX2 and FX3 swapped.
This is the one to go for if you’re recording and want to sound like
you’re running several effects pedals into a cabinet.
This configuration is order 6 with FX2 and FX3 swapped.
