GFX-65
GUITAR AMPLIFIER WITH
DIGITAL SIGNAL PROCESSING
USER’S GUIDE
Congratulations!
You are now the proud owner of the Crate GFX-65 guitar amplifier. This rugged
amplifier delivers serious clean and distorted sounds through its premium 12” Crate
Custom speaker. An easy to operate DSP section lets you dial in a variety of digital
effects such as delay, flange, chorus and reverb – with separate level control. Channel
selection and Crate’s exclusive Shape circuit are controllable by the supplied two-button
footswitch. An insert jack allows virtually noise-free connection of your favorite effects.
Like all Crate products, your GFX-65 is designed by musicians and built using only
the best components. Extensive testing at the hands (and ears) of skilled technicians
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 read this
user’s guide before you begin playing.
And thank you for choosing

There are two variations per effect, as follows:
22: FUSE (rear panel, not shown): The fuse
protects the amplifier against damages caused
by power overload conditions. If the fuse fails,
replace it only with the same size and type fuse.
If the fuse fails repeatedly check the AC source;
if it’s okay, contact your Crate dealer for service
information.
• Slapback delay
• Long delay w/regeneration
• Light Flange
• Heavy Flange
• Slow Chorus
• Fast Chorus
• Chorus w/small room reverb
• Chorus w/large room reverb
• Small room reverb
• Large room reverb
Connecting to the Insert jack:
The Insert jack (#16) lets you patch external
effects into the amplifier just prior to its power
amp stage. Use Crate’s STP201, STP202 or
STP203 stereo-to-mono Y-cord or an adapter
such as Crate’s YPP117 and 2 1/4” mono signal
cables to connect to the effect as shown below.
16: INSERT: Use this jack to connect an exter-
nal effects device to the amplifier. Use a stereo
1/4” male Y-cord: ring = send, tip = return, sleeve
= ground. See the illustration to the right for
more information.
Stereo-to-mono Y-cord:
Y-adapter and 2 cables:
17: EXT. SPEAKER: Use this jack to connect an
extension speaker cabinet to the amplifier. This
jack is wired in series with the internal speaker.

19: POWER ON LED: This LED illuminates
when the amplifier is turned on.
20: POWER SWITCH: Use this switch to turn
the amplifier on (top of the switch depressed) an
off (bottom of the switch depressed).
21. POWER CORD (rear panel, not shown):
The grounded power cord should only be
plugged into a grounded power outlet that meets
all applicable electrical codes and is compatible
with the voltage, power and frequency require-
ments stated on the rear panel. Do not attempt
to defeat the safety ground connection!
