Front Panel Functions

1. Input Jack- High impedance input to the amplifier. Plug in your instrument here.
2. Push/Pull Treble Control- Adjusts the high frequency response. In the full counter-clockwise
position, high frequencies are bypassed to ground. In the full clockwise position, high frequencies
are allowed to pass to the next gain stage. When the knob is in the "out" position, the high
frequency response is boosted. This is most effective when the input gain is set at 12 o'clock or
lower. The effect is less dramatic as the input gain control is adjusted past the 12 o'clock position.
3. Middle Control- Adjusts the mid-range response. In the full counter-clockwise position, the
tone will be somewhat "scooped" of mid-range response, emphasizing the highs and lows. In the
full clockwise position, mid-range frequencies are allowed to pass to the next gain stage.
4. Bass Control- Adjusts the bass response. In the full counter-clockwise position, low
frequencies are cut. In addition, the response of the treble and mid-range controls is greatly
reduced. In the full clockwise position, low frequencies are allowed to pass to the next gain stage.
5. Input Gain- Adjusts the overall gain of the amplifier. Start with this control in the 12 o'clock
position. Keep in mind that the amount of gain set here determines the signal level feeding the
lead channel. Low gain settings of this control will require higher lead gain settings for the same
amount of overdrive.
6. Master Volume- Adjusts the output level of the clean and lead channels.
7. Lead Gain- Adjusts the input level (gain) of the lead channel.
8. Lead master- Adjusts the output level of the lead channel.
9. Reverb- Mixes the dry signal with a high quality spring-type reverberation effect. This effect is
defeated with the control in the full counter-clockwise position.
10. Stand-by Switch- Should be in the "down" or "stand-by" position when you apply power to the
unit. After a few seconds, place the switch in the "up" position to use the amplifier. You may leave
the unit "powered up" and place this switch in the "stand-by" position to mute the output.
11. Indicator Lamp- This lamp will illuminate when the power switch is in the "up" position,
indicating the unit is receiving A/C power.
