GX-120OH Amplifier

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 (#21) over- rides 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 out- put, 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 cre- ate 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 (#21) 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 out- put; 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 out- put; to the right increases it. This control allows a range of 28dB at 10kHz.

14:REVERB LEVEL: Adjust the amount of reverberation with this control: in the full-left position the output signal is “dry” (no reverb); rotating the control to the right increases the amount of reverb. Reverb can be turned on and off with a footswitch (#22).
