FRONT PANEL FUNCTIONS
1. INPUT JACK- High impedance input to the amplifier. Plug in your
instrument here.
2. 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.
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. MID SWITCH- Boost the mid range frequency response.
6. DEEP SWITCH- Boosts the low and low-mid frequencies. This is a low
frequency contour switch, changing the low and low-mid response.
7. 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.
8. CLEAN CHANNEL MASTER VOLUME- Adjusts the output level of the clean
channel.
9. BRIGHT SWITCH- Boosts the high frequency response. 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.
