Input Jack
- High impedance input to the amplifier. Plug in your instrument here.
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.
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 fre-
quencies are allowed to pass to the next gain stage.
For 35 Watt versions
, when the knob is in the “out” position,
the mid range frequency response is boosted.
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.
For 35 Watt versions
, when the knob is in the “out” posi-
tion, the low and low-mid frequencies are boosted. This is a low frequency contour switch, changing the low and
low-mid response.
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.
On 35 Watt versions
, this
control will pull out to activate the BYPASS feature.
Master Volume
- Adjusts the output level of the clean and lead channels.
On 35 Watt versions
, this control will
pull out to activate the LEAD channel.
Lead Gain
- Adjusts the input level (gain) of the lead channel.
Lead master
- Adjusts the output level of the lead channel.
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.
Indicator Lamp
- This lamp will illuminate when the power switch is in the “up” position, indicating the unit is
receiving A/C power.
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.
Indicator Lamp
- This lamp will illuminate when the power switch is in the “up” position, indicating the unit is receiving
A/C power.
