OWNER’S MANUAL

GFX-15

GUITAR AMPLIFIER WITH

DIGITAL SIGNAL PROCESSING

Congratulations!

You are now the proud owner of the Crate GFX-15 guitar amplifier. This small but

versatile amplifier features two separate channels – one crystal clear and the other

with our patented “Flex-Wave” distortion – combined with a three-band EQ and an

easy to operate DSP section which lets you dial in a variety of digital effects such as

delay, flange, chorus and reverb. A special damping circuit simulates the “current

source” type output of a tube amp, giving you solid state reliability combined with clas-

sic tube sounds.

Like all Crate products, your GFX-15 is designed by musicians and built using

only the best components. Extensive testing at the hands (and ears) of skilled tech-

nicians and musicians insures you that this amplifier is the absolute best it can be.

In order to get the most out of your new amplifier, we strongly urge you to go over

the information contained in this manual before you begin playing.

And thank you for choosing

GFX-15 Amplifier

Important Safeguards and Precautions:

All Crate products are designed for continuous safe operation, as long as common sense is

used and steps are taken to help avoid certain problems. Abiding by the following rules can

help prevent damage to your amplifier, yourself and others.

• The amplifier is equipped with a three-pronged AC power cord. To reduce the

risk of electrical shock, NEVER remove or otherwise attempt to defeat the

ground pin of the power cord.

• Connect the amplifier ONLY to a properly grounded AC outlet of the proper volt-

age for your amp.

• Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and

intense impact. (If the unit has been subjected to any of the preceding abuses,

have it looked at by an authorized service center.)

• NEVER set the amplifier on a support that might give out under its weight.

• Always keep the total speaker impedance at or above the rated load.

• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the

amplifier. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film.

• Do not use the amplifier if it has sustained damage to the chassis, controls, or

power cord. Refer the unit to an authorized service center for inspection.

• Amplifiers capable of producing high volume levels are also capable of inflicting

permanent hearing loss or damage, if the exposure to such levels is prolonged.

Such damage is progressive and irreversible! Consider using quality hearing

protection devices.

IMPORTANT SAFETY INSTRUCTIONS

• READ, FOLLOW, HEED, AND KEEP ALL INSTRUCTIONS AND WARNINGS.

• DO NOT OPERATE NEAR ANY HEAT SOURCE AND DO NOT BLOCK ANY VENTILATION OPENINGS ON THIS APPARATUS. FOR

PROPER OPERATION, THIS UNIT REQUIRES 3” (75mm) OF WELL VENTILATED SPACE AROUND HEATSINKS AND OTHER AIR

FLOW PROVISIONS IN THE CABINET.

• DO NOT USE THIS APPARATUS NEAR SPLASHING, FALLING, SPRAYING, OR STANDING LIQUIDS.

• CLEAN ONLY WITH LINT-FREE DAMP CLOTH AND DO NOT USE CLEANING AGENTS.

• ONLY CONNECT POWER CORD TO A POLARIZED, SAFETY GROUNDED OUTLET WIRED TO CURRENT ELECTRICAL CODES AND

COMPATIBLE WITH VOLTAGE, POWER, AND FREQUENCY REQUIREMENTS STATED ON THE REAR PANEL OF THE APPARATUS.

• PROTECT THE POWER CORD FROM DAMAGE DUE TO BEING WALKED ON, PINCHED, OR STRAINED.

• UNPLUG THE APPARATUS DURING LIGHTNING STORMS OR WHEN UNUSED FOR LONG PERIODS OF TIME.

• ONLY USE ATTACHMENTS, ACCESSORIES, STANDS, OR BRACKETS SPECIFIED BY THE MANUFACTURER FOR SAFE OPERA-

TION AND TO AVOID INJURY.

• THIS APPARATUS DOES NOT OPERATE NORMALLY AND REQUIRES SERVICE WITH ANY PHYSICAL DAMAGE FROM IMPACT OR

ANY EXPOSURE TO MOISTURE.

• SERVICE MUST BE PERFORMED BY QUALIFIED PERSONNEL.

• OUR AMPLIFIERS ARE CAPABLE OF PRODUCING HIGH SOUND PRESSURE LEVELS. CONTINUED EXPOSURE TO HIGH SOUND

PRESSURE LEVELS CAN CAUSE PERMANENT HEARING IMPAIRMENT OR LOSS. USER CAUTION IS ADVISED AND EAR PRO-

TECTION IS RECOMMENDED IF UNIT IS OPERATED AT HIGH VOLUME.

CAUTION

GFX-15 Amplifier

1: INPUT: Connect your guitar here by means of a

shielded instrument cable.

OVERDRIVE CHANNEL: A high gain channel giving

you sounds from a slight edge to serious overdrive.

2: GAIN: Use this control to adjust the amount of com-

pression and distortion from the amplifier. With the con-

trol fully counter clockwise, the sound will have a thick

compressed quality. As you rotate the control clockwise

the amount of distortion increases. Crate’s exclusive

“Flex-Wave” circuitry uses sequential cascading gains

to deliver distortion which is rich in harmonics and

“touch sensitive.” Use this control along with the Level

(#3) to create a wide variety of sounds.

3: LEVEL: Use this control to adjust the output volume

level from the Overdrive channel: With the control fully

counter clockwise there will be no output. As you rotate

the control clockwise the output increases. Use this

control along with the Gain control (#2) to create a wide

variety of sounds.

4: OVERDRIVE SELECT: This switch, when

depressed, activates the Overdrive channel. With this

switch in the out position the Clean channel is activated.

CLEAN CHANNEL: A normal gain channel designed

to give you crystal clear sounds to medium distortion.

5: LEVEL: Use this control to asjust the output volume

level from the Clean channel: with this control fully

counter clockwise there will be no output. As you rotate

this control clockwise the output level increases. For the

best results, reduce the Low control (#6) when this con-

trol is near the fully clockwise position.

EQUALIZATION

6: LOW: Use this control to adjust the low frequency

output level. Rotating this control counter clockwise

reduces the low frequency output, rotating it clockwise

increases the low frequency output. The Low control

allows a total range of 25dB of boost or cut at 80Hz.

Due to the massive amount of low end available, this

control should be reduced when playing at high volume

levels.

7: MID: Use this control to adjust the mid frequency out-

put level. Rotating this control counter clockwise

reduces the mid frequency output, rotating it clockwise

increases the mid frequency output. The Mid control

allows for 19dB of boost or cut at 900Hz.

8: HIGH: Use this control to adjust the high frequency

output level. Rotating this control counter clockwise

reduces the high frequency output, rotating it clockwise

increases the high frequency output. The High control

allows a total range of 23dB of boost or cut at 5kHz.

9: DSP MODE: Use this control to select the digital

effect. Each category and its central location is called

out (delay, flange, etc.) by the markings around the

control, with variations, as follows:

• Bypass (DSP off)

• Slapback delay

• Long delay w/regeneration

• Flange

• Slow Chorus

• Fast Chorus

• Chorus w/small room reverb

• Small room reverb

• Large room reverb

10: HEADPHONES: For private practice sessions, plug

a pair of stereo headphones into this jack. The internal

speaker is disconnected whenever headphones are

being used.

11: EXTERNAL SPEAKER: Use this jack to connect

the GFX-15 to an external speaker with a rated imped-

ance of at least 4 ohms. The internal speaker is discon-

nected whenever an external speaker is used.

WARNING: Do not use headphones in the Speaker

jack. Serious hearing damage could occur!

12: ON LED: The on LED illuminates when the amplifi-

er is on.

13: POWER: Use this switch to turn the amplifier on

(top of the switch depressed) and off (bottom of the

switch depressed).

14: POWER CORD (rear panel, not shown): This

grounded power cord is to be plugged into a ground-

ed power outlet, wired to current electric codes and

compatible with voltage, power, and frequency

requirements stated on the rear panel. Do not

attempt to defeat the safety ground connection.
