Welcome!

Thank you for making the Alesis GuitarFX a part of your setup. Since 1984,

we've been designing and building creative tools for the audio community. We

believe in our products, because we've heard the results that creative people like

you have achieved with them. One of Alesis' goals is to make high-quality music

equipment available to everyone, and this user manual is an important part of that.

After all, there's no point in making equipment with all kinds of capabilities if no

one explains how to use them. So, we try to write our manuals as carefully as we

build our products.

The goal of this manual is to get you the information you need as quickly as

possible, with a minimum of hassle. We hope we've achieved that. If not, please

drop us an email and give us your suggestions on how we could improve future

editions of this manual.

We hope your investment will bring you many years of creative enjoyment and

help you achieve your musical goals.

Sincerely,

The people of Alesis

About the GuitarFX

The first thing you’ll probably notice about the GuitarFX is

its size—it’s not that much larger or smaller than most other

guitar effects pedals. But don’t let that fool you. The

GuitarFX does much more than most pedals you’ll find on

the market today (and for an unbeatable price too). We’ve

packed a lot of effects (more than 40!) and features into this

unit. Here’s a glimpse:

GuitarFX Key Features

• 80 preset patches that you can fully edit, store and

restore to the factory default settings

• 9 effect modules that provide multiple selectable effects

• Over 40 different effects with adjustable parameters and

innumerable effect combinations

• Built-in auto-chromatic tuner

• Battery-powered operation and an external power

option (9VDC)

• Simple interface that gives you quick and easy access to

the GuitarFX’s features

GuitarFX Basics

Benefits of a Multi-Effects Pedal

If you’ve ever used guitar pedals, you know they come in an

infinite array of effects, colors and sizes. If you use multiple

pedals, you probably do so by linking them all together into a

chain. The GuitarFX eliminates the need for so many pedals

because it combines just about all the effects you need into

one unit. Instead of turning knobs and pushing buttons on

pedal after pedal, with the GuitarFX you have full control

over dozens of effects with one foot pedal! It’s that easy.

Introduction

Effect Modules

If you were to think of the GuitarFX as a series of individual

pedals linked together, then each pedal in that series would be

considered an effect module. The GuitarFX has nine separate

effect modules, as shown below:

You can assign one effect to each of these modules and

adjust its parameters accordingly. On the face of the unit,

you’ll see a list of possible effect types for some of these

modules. For more on 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,

FDR 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.

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 effects modules

and their respective settings. In PLAY mode,

you have quick access to the GuitarFX’s 80

programs via the foot pedals 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.

How to Use This Manual

This manual is divided into the following sections describing

the various functions and applications for the GuitarFX.

While it's a good idea to read through the entire manual once

carefully, if you already have general knowledge about guitar

effects, you should use the table of contents to look up

specific functions.

Chapter 3: Getting Started shows you how to get the unit

connected and turned on. We’ve included a hookup diagram

and some tips on using the GuitarFX.

Chapter 4: A Tour of the GuitarFX describes all the controls and

features of the unit. This chapter features diagrams of the top

and rear panels that are labeled with the name and a brief

overview of each function. The paragraphs that follow the

diagrams provide more in-depth discussion of these features.

Chapters 5 through 9 include step-by-step instructions for using

the GuitarFX, including how to select and edit programs, use

the tuner function, store and copy programs, and defer

program changes.

Chapter 10: Effects Knob Settings explains the unit’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 GuitarFX. 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: Warranty/Contact Alesis explains the warranty we

supply with the GuitarFX and lets you know the best way to

reach us if you have any questions or comments.

3 Hookup Diagram

14

The first thing we’ll show you is how to get your GuitarFX

up and running. The following diagram shows you the most

common method of hooking up your GuitarFX, but there are

other ways of doing it. For example, you may decide to run

the GuitarFX straight into your mixer or recording device

instead of an amplifier (that’s what we had in mind when we

created those great cabinet simulator effects). You may even

want to go so far as to use the GuitarFX to add effects to

keyboards or other electronic instruments.

Although you can

experiment with

different types of

instruments, the

GuitarFX performs best

with a guitar, as it was

made specifically to

handle that

instrument’s frequency

range.

When you plug an

adapter into the

GuitarFX while

batteries are in the unit,

it will be powered by

the adapter and not the

batteries.

Top Panel

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

When either of the

decimal points on the

display is flashing,

battery power is low

and about to run out.

A Tour of the GuitarFX

16

GuitarFX’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 6 “Editing Programs” and

chapter 7, “Using the Tuner.”

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 GuitarFX.

Refer to chapter 10 for descriptions of the possible values for

the EFFECT knob’s settings.

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.

Foot Pedals

While in PLAY mode, the left foot pedal decrements the

program number, and the right foot pedal increments the

program number. When you press both pedals together, the

GuitarFX goes into bypass mode, in which the audio signal

from your guitar simply passes through the GuitarFX without

being affected. When you hold both foot pedals down for

longer then half a second, the GuitarFX goes into mute mode,

in which no signal at all leaves the GuitarFX. When you are in

bypass or mute mode, the tuner is activated.

While in PLAY mode, if

you press and hold the

VALUE knob for longer

than half a second, the

display will change to

the current master

volume setting (1 to 30).

Default volume is 21

(unity gain) and each

number indicates a 2dB

change from the

number above or below

it. Unlike LEVEL,

which indicates the

level of an individual

program, the master

volume is a global

setting that is

remembered each time

the unit is turned off.

Rear Panel

The rear panel is where you’ll connect the power source, your

guitar and amplifier and an optional control pedal. It’s

important that you use the right types of plugs in these jacks.

Be sure to follow these guidelines.

5 Selecting Programs

18

After you’ve plugged everything in, you’ll probably want to

check out the factory presets we programmed into the

GuitarFX. This chapter shows you how to do that.

To Select Programs

1. Make sure the GuitarFX is

hooked up properly and turned

on, as outlined in chapter 3.

2. Make sure you’re in PLAY

mode (turn the EFFECT knob

to PLAY).

3. You can switch programs in

two different ways:

Foot pedals

This is the easiest way to switch

programs, especially while

playing your guitar. Just step on

the left foot pedal

to

decrement the program number

and the right

to increment it.

You can hold down a pedal to

increment or decrement

programs continuously.

VALUE knob

You also can turn this knob to switch programs.

4. Play your guitar to see how the program affects the

sound.

6 Editing Programs

19

To Edit a Selected Program

1. Select a program to edit using the

foot pedals or VALUE knob.

2. Turn the EFFECT knob to the

effect module or parameter you

wish to modify.

3. Turn the VALUE knob to select

an effect type or value for the

module. As soon as you change

the value, the EDITED decimal

point on the display lights up to

show you a change has been

made to the current program.

4. If the module has a parameter

such as DRIVE or PARAM,

turn the EFFECT knob to

select the parameter.

5. Using the VALUE knob, select a

value for the parameter.

6. Continue in this way until you have completed

assignments for all modules and parameters.

To Restore Factory Presets

Once you have saved changes to a preset program, you can

still recall the original settings. To enter the RESTORE

FACTORY PRESETS mode, simply hold down the VALUE

knob as you turn the unit on and then select the program to

be restored (or AL for all programs). Press the VALUE knob

to confirm your selection. Any program changes you have

made will be lost, so you might want to copy the program to

another location first.

Just turn the EFFECT

knob to exit the

RESTORE FACTORY

PRESETS mode, or

turn the unit off and

then on again.

To toggle an effect

module on and off,

press both pedals while

the effect module is

selected.

7 Using the Tuner

20

To Tune Your Guitar

1. In PLAY mode, enter BYPASS

or MUTE mode by

pressing both foot pedals 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. Make sure your guitar is

connected to the GuitarFX, 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.

3. 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 you what

you’ll see on the display while tuning your guitar.
