1: INPUT: Connect your guitar here using a shielded instrument cable. OVERDRIVE CHANNEL: A high gain channel giving you sounds from a slight edge to serious overdrive. 2: GAIN 1: When active, sets the amount of compression and distortion from the amplifier. At far left, the sound will have a thick compressed quality. As you turn the control to the right the amount of distortion increases. Gain 1 produces less intense distortion than Gain 2 and is active only when the Gain Select switch (#5) is out. 3: GAIN 2: When active, sets the amount of compression and distortion from the amplifier. At far left, the sound will have a thick compressed quality. As you turn the control to the right the amount of distortion increases. Gain 2 produces more intense distortion than Gain 1 and is active only when the Gain Select switch (#5) is in. 4: SHAPE: Working in conjunction with the Gain 2 control, rotate the Shape control until you find the sound you�re looking for. Turning the control towards the left enhances the mid frequencies; turning it to the right enhances the low and high frequencies. (Only affects Gain 2 when active.) 5: GAIN SELECT: Switches between Gain 1 (out) and Gain 2 (in). A footswitch (#22) overrides this switch. 6: LOW: Adjusts the low frequency output level: to the left reduces the low frequency output; to the right increases it. This control allows a range of 11dB at 80Hz. 7: HIGH: Adjusts the high frequency output level: to the left reduces the high frequency output, to the right increases it. This control allows a range of 10dB at 10kHz. 8: LEVEL: Sets the output volume level from the Overdrive Channel: in the far-left position there is

no output; turning the control to the right increases the output. Use this control along with the Gain and Shape controls (#2, 3 & 4) to create a wide variety of sounds. 9: CHANNEL SELECT: When this switch is pressed in the Overdrive Channel is engaged. The Clean Channel is selected when this switch is out. A footswitch (#22) overrides this switch. The adjacent LEDs indicate which channel is selected. CLEAN CHANNEL: A normal gain channel designed to give you crystal clear sounds. 10: LEVEL: Sets the output volume level from the Clean Channel: in the far-left position there is no output; turning the control to the right increases the output level. 11: LOW: Adjusts the low frequency output level: to the left reduces the low frequency output; to the right increases it. This control allows a range of 22dB at 80Hz. 12: MID: Adjusts the mid frequency output level: to the left reduces the midrange output; turning it to the right increases it. This control allows a range of 14dB at 600Hz. 13: HIGH: Adjusts the high frequency output level: to the left reduces the high frequency output; to the right increases it. This control allows a range of 28dB at 10kHz. 14: DSP LEVEL: Adjust the amount of digital signal processing with this control: in the full-left position the output signal is �dry� (no effect); rotating the control to the right increases the amount of effect. The DSP can be turned on and off with a footswitch (#23). 15: DSP MODE: Select the type of digital effect(s) desired with this control. Each category and its central location is called out (delay, flange, etc.) by the markings around the control; there are two variations per effect, as follows:

� Slapback delay � Long delay w/regeneration � Light Flange � Heavy Flange � Slow Chorus � Fast Chorus � Chorus w/small room reverb � Chorus w/large room reverb � Small room reverb � Large room reverb 16: INSERT: Connect an external effects device via this jack. Use a stereo 1/4� male Y-cord: ring = send, tip = return, sleeve = ground. See the illustration on the panel to the right for more information. 17: EXT. SPEAKER: Connect to jack is wired in speaker cabinet with this jack. The an extension series with the internal speaker(s). 18: POWER ON LED: Lights when the amplifier is turned on. 19: POWER SWITCH: Turns the amplifier ON in the up position, off in the down position. 20. POWER CORD (rear panel, not shown): Your GFX-120/212 is equipped with a heavy-duty 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 connection on this cord. 21: FUSE (rear panel, not shown): Protects the 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.

22: CHANNEL SELECT / GAIN FOOTSWITCH JACK (rear panel, not shown): Connect the stereo 1/4� plug of the supplied three-button footswitch here for remote control of the Channel Select and Gain Select settings. 23: DSP FOOTSWITCH JACK (rear panel, not shown): Connect the mono 1/4� plug of the supplied three-button footswitch here for remote control of the DSP on and off. Connecting to the Insert jack: The Insert jack (#16) lets you patch external effects into the amplifier just prior to its power amp stage. Use Crate�s CYC6MS stereo-to-mono Y-cord or an adapter such as Crate�s CA11Y and 2 1/4� mono signal cables to connect to the effect as shown below.
