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

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.

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!
