Congratulations! You are now the proud owner of the Crate GTX3500H TidalWave 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 Tap/Save 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.
The Front Panel: 1 2 3 4 5 6 7 9 8 10 12 11 13 14 1. 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. 2. REV: Use this control to adjust the amount of the digital reverb effect. In its fully counter clockwise position the signal is “dry” (without any reverb). As you rotate the control clockwise the amount of reverb increases.

HIGH: Use this control to adjust the high frequency level of Channel 3. 13. MID: Use this control to adjust the midrange frequency level of Channel 3. 14. LOW: Use this control to adjust the low frequency level of Channel 3. 15.
The Rear Panel: 28 29 30 31 32 28. LINE OUT: When using an external effects processor, connect this jack to the input of the effect by means of a shielded signal cable. This jack also doubles as a source for a post-EQ, preamp signal to send your signal to a mixing board, recorder, powered monitor or external amplifier. 29. LINE IN: When using an external effects processor, connect this jack to the output of the effect by means of a shielded signal cable.
The DSP Section: The GTX3500H features DSP controls for Reverb, Delay and Multi. Complete information about the Delay and Multi effects is given below. The Delay control selects the delay or echo effects. All of these effects have their speed controlled by the Tap/Save button. The Multi control selects the “pitch modified” and wah effects. Many of these effects have their speed controlled by the Tap/Save button. Additional information is provided on pages 5 and 10.
Storing Your Own Presets: Each channel of the GTX3500H has two factory assigned Effects presets, as shown on pages 10 and 11. No matter what the settings of the Rev, Delay and Multi controls, the DSP and reverb presets are recalled when a channel is selected. You may change the DSP and reverb settings by rotating the Rev, Delay and Multi controls - these changes will remain active until a different channel is selected, but will not be there for later use unless they are saved.
Using the Footswitch: The special Crate four-button footswitch supplied with the GTX3500H performs a variety of functions. The footswitch allows remote channel selection, remote Tap/Save for each channel, and allows access to an additional DSP preset for each channel of the amplifier. Use only the supplied Crate four-button momentary footswitch with the GTX3500H. A standard 5-wire midi cable (supplied) may be used to connect the footswitch to the amplifier.
