GTD120/212 Guitar Amplifier w/DSP and Channel Tracking
Introduction
Congratulations! You are now the proud owner of the Crate GTD120/212 three-channel guitar
amplifier with advanced digital signal processing (DSP) and Channel Tracking. This rugged
amplifier combines outstanding features with serious clean and distorted sounds. Digital
Reverb, Chorus, and Delay provide you with a wide variety of sounds. Crate’s unique Channel
Tracking feature automatically stores your DSP settings for each channel to memory. As you
switch from one channel to another, the DSP settings for the selected channel are instantly
recalled. The supplied three-button footswitch allows you to select channels and change the
DSP bank (Bank A/Bank B) by “remote control.” A front panel 1/8" stereo CD input jack allows
you to play along with your CD player, MP3 player, or iPod. A rear panel insert jack allows you
to add even more effects by connecting an external effect processor.
Like all Crate products, your GTD amplifier is designed by musicians and built using only the
best components. Extensive testing confirms 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 manual
before you begin playing.
And thank you for choosing Crate.

Channel Tracking
Your Crate GTD120/212 gives you the power of Channel Tracking. Once you select a DSP
setting for each channel, Channel Tracking stores the settings to memory whenever you
change channels. When you go back to that channel, Channel Tracking recalls those DSP settings automatically, without changing the DSP controls!
For example:
• Select the Clean channel. Set the Chorus control to “Flanger,” the Delay control to “Echo,”
and adjust the Reverb control to your preference.
• Select the Overdrive channel. Set the Chorus control to “Chorus,” the Delay control to
“Slap,” and readjust the Reverb control to a different setting. (The DSP settings for the
Clean channel are now saved to memory.)
• Select the High Gain channel. Set the Chorus control to “Phaser,” the Delay control
to “Echo/Eff,” and readjust the Reverb control once again. (The DSP settings for the
Overdrive channel are now saved to memory.)
• Reselect the Clean channel. (The DSP settings for the High Gain channel are now saved to
memory.)
When you reselected the Clean channel, the DSP settings previously stored in memory were
automatically recalled. Switch to the Overload channel and the DSP settings you just stored
are still there. You can change the DSP settings at any time. Once you set the DSP and select
another channel, Channel Tracking stores the settings for you. Even when the amplifier is
turned off, the DSP settings are stored and recalled the next time you turn it on. That’s the
power of Channel Tracking!
In addition, each channel has two DSP banks, Bank A and Bank B, when you use the supplied
three-button footswitch (see page 8 for more information on using the footswitch). Channel
Tracking also remembers which DSP bank was selected for each channel.

1. INPUT: Use this jack to connect your
guitar to the amplifier by means of a shielded instrument cable.
2. HIGH GAIN LED: This LED illuminates
when the High Gain channel is selected.
3. GAIN: Use this control to adjust the amount
of distortion for the High Gain channel.
4. SHAPE: Use this control to “dial in” the
tone for the High Gain channel. Rotating
this control counter-clockwise enhances the
mid frequencies, while rotating it clockwise
enhances the low and high frequencies.
5. LEVEL: Use this control to adjust the output level of the High Gain channel.
6. HIGH GAIN/OVERDRIVE: Use this switch
to select the High Gain or Overdrive channel. With the switch in the out position, the
Overdrive channel is selected. When the
switch is pushed in, the High Gain channel is
selected. Note: This switch is only active when
the Overdrive/Clean switch [13] is pushed in.
7. OVERDRIVE LED: This LED illuminates
when the Overdrive channel is selected.
8. GAIN: Use this control to adjust the amount
of distortion for the Overdrive channel.
9. LOW: This adjusts the bass frequencies.
Use this control to get the best sounding
bass response for your instrument when
using the Overdrive channel.
10. MID: This adjusts the midrange frequencies. Use this control to get the best projection and midrange tones for your instrument
when using the Overdrive channel.
11. HIGH: This adjusts the treble frequencies. Use this control to attain a bright and
lively sound for your instrument when using
the Overdrive channel.
12. LEVEL: Use this control to adjust the
output level of the Overdrive channel.

13. OVERDRIVE/CLEAN: Use this switch
to select the Clean channel or the Overdrive
and High Gain channels. With the switch in
the out position, the Clean channel is selected. When the switch is pushed in, either the
High Gain or Overdrive channel is selected,
depending on the setting of the High Gain/
Overdrive switch [6].
14. CLEAN LED: This LED illuminates when
the Clean channel is selected.
15. VOLUME: Use this control to adjust the
output level of the Clean channel.
16. LOW: This adjusts the bass frequencies. Use this control to get the best sounding bass response for your instrument when
using the Clean channel.
17. MID: This adjusts the midrange frequencies. Use this control to get the best projection and midrange tones for your instrument
when using the Clean channel.
18. HIGH: This adjusts the treble frequencies. Use this control to attain a bright and
lively sound for your instrument when using
the Clean channel.
19-21. EFFECTS: Use these controls to apply
and adjust the DSP effects. Complete information on these effects is provided on page 7.
22. CD INPUT: Use this 1/8" stereo mini
jack to connect the output from a CD player,
MP3 player, laptop, etc., to the amplifier.
The signal at this jack is summed into a
mono signal, which is sent to the internal
power amp circuit. Use the output level control for the signal source to adjust the signal
for the proper mix with your guitar.
23. POWER: Use this switch to turn the
amplifier on (top of the switch depressed)
and off (bottom of the switch depressed).
The switch illuminates when the amplifier is
turned on.

Using the Footswitch with the DSP
The Crate three-button footswitch supplied with the GTD120/212 allows access to an additional DSP preset for each channel of the amplifier. When the footswitch is connected to the
amplifier as shown below, the “original” DSP presets are active for each channel when the #3
footswitch LED is illuminated. These are referred to as “DSP Bank A.” When the #3 button is
switched and the LED is off, a second DSP preset may be stored and recalled for each channel — “DSP Bank B.”
Note: DSP Bank B presets are only accessible when the footswich is connected to the amplifier. When the footswitch is not connected, only DSP Bank A is accessible.
