The Front Panel:
1. Input: Connect your instrument
here by means of a shielded signal
cable.
2. Gain: Use this control to adjust
the input gain. With the control
towards the counter clockwise position, the gain is low and very little
distortion is present. As you rotate
the control clockwise the gain
increases, producing more overdrive distortion and a higher output
volume level.
3. Boost: This switch, when
depressed, increases the output of
the frequencies below 500Hz, giving
the bottom end more punch.
4. Treble: Use this control to adjust
the output level of the high frequencies. This control provides 8dB of
cut or boost at 10kHz.
5. Mid: Use this control to adjust the
output level of the middle frequencies. This control provides 9dB of
cut or boost at 700Hz.
6. Bass: Use this control to adjust
the output level of the low frequencies. This control provides 12dB of
cut or boost at 60Hz.
7. Level: Use this control to adjust
the output level of Channel B.
8. Reverb: Use this control to adjust
the amount of reverberation applied
to the signal. With the control fully
counter clockwise no reverb is
applied. As you rotate the control
clockwise the reverb increases.
9. Lamp: This lamp illuminates
when the amplifier is turned on.
10. On/Off Switch: Use this switch
to turn the amplifier on and off.
