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 cut. In the full clockwise position, high frequencies are allowed to
pass to the
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
gain control is adjusted past the 12 o’clock position.
3. Push/Pull Mid 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 gain stage. When the
knob is in
the “out” position, the EQ section is passively bypassed boosting the natural high and
mid frequencies of the guitar. It also increases the amount of input signal that drives the gain
stage. (Push/Pull not available in 22 watt version)
4. Push/Pull 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 gain stage.
When the knob is in the “out” position, the low and low-mid frequencies are boosted. This is a low
frequency contour switch, changing the low and low-mid response.
(Push/Pull not available in 22
watt version)
5. Gain
-
Adjusts the overall gain of the amplifier. Start with this control in the 12 o’clock position.
6. Master Volume
- Adjusts the output level of the amplifier. Also acts as the send level control for
any effects inserted in the loop.
7. Reverb Send
- The reverb drive control determines the amount of signal applied to the reverb
tank. Low settings will create a very open, small room reverb effect with a short decay time.
Advancing the control clockwise increases the signal applied to the driver and a very saturated
effect with a sharp attack and a long decay can be obtained.
8. Reverb return
- The reverb return control mixes the reverb effect signal with the dry signal. At
full counterclockwise rotation, the reverb effect is defeated. Using the return control in conjunction
with the reverb drive control, a wide range of natural reverb effects can be produced.
