GFX-120/212
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.
And thank you for choosing

grounded three-wire power cord. Be sure this cord
is properly plugged into a safely wired grounded
120 volt, 60Hz AC power outlet before use. (If your
GFX-120/212 was purchased outside the United
States, refer to the rear panel for power ratings.)
For your safety, never attempt to defeat the ground

amplifier against damages caused from a faulty AC
power source or other problems. If the fuse blows,
replace it ONLY with the same size and type fuse.
If the fuse blows repeatedly check the AC source;
if it’s okay, contact your Crate dealer for service
information.
