Congratulations!
Y ou are now the proud owner of the Crate GFX-65Tamplifier. This rugged amplifier combines outstanding features with serious clean and distorted sounds. An easy to operate DSPsection lets you dial in a variety of digital effects including reverbs, delays, octave and wah-wahs – with a sepa­rate level control. Crate’s unique Channel T racking feature means that as you switch between channels and gains, the DSP automatically “tracks” the changes - your DSP settings for each channel are stored and automatically recalled! The supplied three-button footswitch allows you to select channels, change the overdrive gain, and turn the DSPon and off by “remote control.” The top-mounted electronic tuner lets you get tuned and stay in tune any time the amplifier is on.
Like all Crate products, your GFX-65T 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 the informa­tion contained in this manual before you begin playing.
And thank you
for choosing

GFX-65T Guitar Amplifier with DSP & Channel Tracking
Channel T
racking:
Your Crate GFX-65T gives you the power of Channel Tracking! Once you select a DSP setting for each channel, Channel Tracking recalls those DSP settings automatically – without changing the DSP controls! For example:
Select the Clean channel. Set the DSP Mode to “FLNG 1”
(slow flange + reverb)
Select the Overdrive channel, Gain 1. Set the DSP Mode to “CHO 1”(slow chorus + reverb) (the set-
ting for the Clean channel is now saved to memory)
Select the Overdrive channel, Gain 2. Set the DSP Mode to “T-WAH” (touch wah-wah) (the setting
for the Overdrive channel, Gain 1 is now saved to memory)
• Reselect the Clean channel (the setting for the Overdrive channel, Gain 2 is now saved to memory)
Now when you go back to the Clean channel, even though the DSP Mode was last set to “T-WAH,” Channel Tracking automatically recalls the last setting for the Clean channel – in this example, “FLNG 1.” Change to the Overdrive channel, Gain 1, and “CHO 1” is recalled. Change to the Overdrive channel, Gain 2, and “T-WAH” is recalled. That’s the power of Channel Tracking!
(Note: Even when the power is turned off, Channel T racking still retains the settings – until you change them!)
1 REV 1 small room reverb 2 REV 2 medium room reverb 3 REV 3 large room reverb 4 REV 4 concert hall reverb 5 DLY 1 short slapback + small room reverb 6 DLY 2 medium delay + plate reverb 7 DLY 3 long delay + large room reverb 8 FLNG 1 slow deep flange + reverb
9 FLNG 2 flange + reverb + delay 10 CHO 1 slow tremolo chorus + reverb 11 CHO 2 chorus + reverb + delay 12 RTRY simulated rotating speaker effect 13 OCTV DN adds a signal one octave lower than input 14 T-WAH touch sensitive wah-wah effect 15 I-WAH inverse wah-wah effect 16 DBLR simulated second track, slightly out-of-sync

1: INPUT : Use this 1/4” jack to connect your guitar to the amplifier by means of a shielded instrument cable.
OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive.
2: GAIN 1: Use this control to adjust the amount of light distortion for the Overdrive channel. Gain 1 pro­duces less intense distortion than Gain 2 (#3) and is active when the Gain switch (#5) is in the out position.
3: GAIN 2: Use this control to adjust the amount of heavy distortion for the Overdrive channel. Gain 2 pro­duces more intense distortion than Gain 1 (#2) and is active when the Gain switch (#5) is depressed.
4: SHAPE: Use this control to “dial in” the tone for the Overdrive channel when Gain 2 is selected. Rotating the control counterclockwise enhances the mid frequencies, while rotating the control clockwise enhances the low and high frequencies. This control is active only when Gain 2 is selected.
5: GAIN SELECT: Use this switch to select which gain control is active for the Overdrive channel. With the switch in the out position, Gain 1 is selected. When the switch is depressed, Gain 2 is selected.
6: LOW: Use this control to adjust the low frequency level of the Overdrive channel. 7: HIGH: Use this control to adjust the high frequency level of the Overdrive channel. 8: LEVEL: Use this control to adjust the output level of the Overdrive channel. 9: CHANNEL SWITCH: Use this switch to select either channel. With the switch in the out position, the
Clean channel is selected. When the switch is depressed, the Overdrive channel is selected.
CLEAN CHANNEL: A normal gain channel designed to give you crystal clear sounds to medium distortion.
10: LEVEL: Use this control to adjust the output level of the Clean channel. 11: LOW: Use this control to adjust the low frequency level of the Clean channel. 12: MID: Use this control to adjust the midrange frequency level of the Clean channel. 13: HIGH: Use this control to adjust the high frequency level of the Clean channel. 14: DSP LEVEL: Use this control to adjust the amount of digital effect: in its fully counterclockwise posi-
tion the signal will be “dry” (without any effect). As you rotate the control clockwise the amount of effect increases.
15: DSP MODE:Use this control to select one of the 16 built-in digital effects. Alisting of the effects is shown on page 3 of this manual.
16: INSERT: Use this jack to connect an external effects device to the amplifier. Use a stereo 1/4” male Y connector: ring = send, tip = return, sleeve = ground. (Refer to the illustration at the bottom of page 5.)
17: EXTERNAL SPEAKER: Use this jack to connect the amplifier to an external speaker. The internal speaker is disconnected when this jack is used. The minimum impedance for the external speaker is 4 ohms.
18: ON LED: This LED will illuminate when power is applied to the amplifier. 19: POWER: Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the
switch depressed).

The Electronic Tuner:

20. ELECTRONIC TUNER (top panel): This active electronic tuner is on whenever the amplifier is turned
on, allowing you constant, “real-time” tuning. The bottom row of LEDs indicate which string is being tuned, while the top row of LEDs are your guiding lights: use the flat and sharp indicators until the center LED illu­minates. This indicates a properly tuned string.
21: AC LINE CORD (rear panel, not shown): This grounded power cord is to be plugged into a ground­ed power outlet, wired to current electrical codes and compatible with the voltage, power, and frequency requirements stated on the rear panel. Do not attempt to defeat the safety ground connection.
21: FUSE (rear panel, not shown): The fuse protects the amplifier from damages caused by a faulty AC power source and/or other problems. If the fuse opens, replace it ONL Ywith the same size and type. If fuses continue to fail, check the AC source – if the source is okay, contact your Crate dealer for serv­ice information.
22: CHANNEL SELECT / GAIN FOOTSWITCH JACK (rear panel, not shown): Use this jack to con­nect the stereo 1/4” plug of the supplied three-button footswitch for remote control of channel selection and gain selection.
23: REVERB FOOTSWITCH JACK (rear panel, not shown): Use this jack to connect the mono 1/4” plug of the supplied three-button footswitch for remote control of DSP on and off.
CONNECTING T
O THE INSERT JACK:
The Insert jack (#16) allows you to patch an external effects device into the amplifier 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 two 1/4” mono signal cables to connect the effect as shown to the immediate right.
