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 input gain stage.
3.
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.
4.
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 input gain stage.
5.
Mid Switch- Boosts the mid range frequency response.
6.
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.
7
. Deep Switch- Boosts the low and low-mid frequencies. This is a low frequency contour switch,
changing the low and low-mid response.
8.
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.
9.
EQ Shift - , the EQ Shift switch is a traditional/modern switch which adjusts the way that the
tone stack passes to the input gain stage. In the up position, the eq curve allows for more
dynamic interaction between treble and bass. In the down position the amount of gain is doubled
and some of the dynamics between the controls are minimized
10.
Master Volume- Adjusts the output level of the amplifier. Both the clean and overdrive output
is controlled by this level. This level will also control how much signal is passed to any pedal that is
inserted into the effects loop.
