GTX65

Three-Channel Guitar Amplifier with Advanced DSP

Congratulations!

You are now the proud owner of the Crate GTX65
three-channel guitar amplifier with Advanced Digital Signal
Processing. This rugged amplifier combines outstanding
features with serious clean and distorted sounds. Dual
DSP controls provide 15 “Multi” effects and 15 Delay
effects which can be combined for a wide variety of
sounds. The Save/Tap button allows you to manually set
the tempo of many of the effects and to save new DSP
presets in the amplifier’s non-volatile memory. A separate
Reverb control adds even more to the array of effects.
Front panel RCA CD Input jacks allow you to play along
with your favorite CD or tape. The rear panel Insert Jack
allows you to connect your effects for greater flexibility.
Channel switching and DSP may be controlled by means
of a footswitch, which also allows access to two DSP pre­sets on each of the three channels.

Like all Crate products, your GTX65 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
suggest that you read the information contained in this guide
before you begin playing.

And thank you for choosing

1: INPUT: Use this jack to connect your guitar to the amplifier by means of a shielded
instrument cable.

SOLO/RHYTHM CHANNELS: High gain channels giving you sounds with serious over­drive.

2: SOLO LED: This LED illuminates when the Solo channel is selected.
3: GAIN: Use this control to adjust the amount of distortion produced by the Solo channel.
4: SHAPE: Use this control to “dial in” the tone for the Solo channel. Rotating the control

counterclockwise enhances the mid frequencies, while rotating the control clockwise
enhances the low and high frequencies.

5: LEVEL: Use this control to adjust the output level of the Solo channel.
6: SOLO/RHYTHM SELECT: Use this switch to select the Solo or Rhythm channel. When

this switch is depressed, the Solo channel is selected. With the switch in the out position,
the Rhythm channel is selected. This switch is active only when the Solo-Rhythm/Clean
Select switch (#13) is depressed.

7: RHYTHM LED: This LED illuminates when the Rhythm channel is selected.
8: GAIN: Use this control to adjust the amount of distortion produced by the Rhythm channel.
9: LOW: Use this control to adjust the low frequency level of the Solo/Rhythm channel.
10: MID: Use this control to adjust the midrange frequency level of the Solo/Rhythm channel.
11: HIGH: Use this control to adjust the high frequency level of the Solo/Rhythm channel.
12: LEVEL: Use this control to adjust the output level of the Rhythm channel.
13: SOLO-RHYTHM/CLEAN SELECT: Use this switch to select the Clean channel or the

Solo and Rhythm channels. With the switch in the out position, the Clean channel is select­ed. When the switch is depressed, either the Solo or Rhythm channel is selected, depend­ing on the setting of the Solo/Rhythm Select switch (#6).

CLEAN CHANNEL: A normal gain channel designed to give you crystal clean sounds.

14: CLEAN LED: This LED illuminates when the Clean channel is selected.
15: VOL: Use this control to adjust the output level of the Clean channel.

16: LOW: Use this control to adjust the low frequency level of the Clean channel.
17: MID: Use this control to adjust the midrange frequency level of the Clean channel.
18: HIGH: Use this control to adjust the high frequency level of the Clean channel.
19: CD INPUT: Use these RCA jacks to connect the output from a CD player or tape deck

to the amplifier. The signal at these jacks is combined into a mono signal which is sent to
the internal power amp circuit. Use the CD or tape player’s output level control to adjust
the signal for the proper mix with your guitar.

20: DSP MULTI: Use this control to select one of the fifteen “Multi” digital effects. Complete
information about the DSP effects is on page 7.

21: DSP DELAY: Use this control to select one of the fifteen Delay digital effects.
Complete information about the DSP effects is on page 7.

22: SAVE/TAP: Use this pushbutton to set the tempo of many of the effects by tapping the
button repeatedly in time with the desired tempo. The Save/Tap button is also used to save
DSP presets and to restore the factory default DSP settings. Additional information about
the Save/Tap button is on pages 7 and 8.

23: SAVE/TAP LED: This LED flashes in time with the tempo set by the Save/Tap button
(#22), and serves as a status indicator for certain DSP activities (see page 8).

NOTE: For some of the DSP effects, the Save/Tap LED remains illuminated. The Save/Tap LED
does not illuminate when the DSP knobs are set to the Bypass position.

24. REVERB: Use this control to adjust the amount of digital reverb effect. In its fully coun­terclockwise position the signal will be “dry” (without any reverb). As you rotate the control
clockwise the amount of reverb increases.

25: 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 power is on.

NOTE: When the amplifier is turned on, the Save/Tap LED flashes for one second before the
amplifier is operational.
