GUITAR AMPLIFIER WITH  
DIGITAL SIGNAL PROCESSING  
OWNER’S MANUAL  
Congratulations!  
You are now the proud owner of the Crate GFX-120/212 guitar amplifier. These  
rugged amplifiers combine outstanding features with serious clean and distorted  
sounds. 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,  
Crate’s exclusive Shape circuit, and DSP on/off are controllable by the supplied three-  
button footswitch. An insert jack allows virtually noise-free connection of your favorite  
effects.  
Like all Crate products, your GFX-120/212 is Musician Made in the U.S.A., using  
only the best components. Extensive testing at the hands (and ears) of skilled techni-  
cians 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.
