GFX-1200H Amplifier
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
1:INPUT: Connect your guitar here using a shield- ed instrument cable.
OVERDRIVE CHANNEL: A high gain channel giv- ing you sounds from a slight edge to serious over- drive.
2:GAIN 1: When active, sets the amount of com- pression and distortion from the amplifier. At far left, the sound will have a thick compressed quali- ty. 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 com- pression and distortion from the amplifier. At far left, the sound will have a thick compressed quali- ty. 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 fre- quencies. (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
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 adja- cent 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
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 sig- nal processing with this control: in the
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:
