The Overdrive Gain control adjusts the amount of the Overdrive Channel's overdrive
or distortion. Low settings, counter clockwise, will deliver a clean sound on the

will become more overdriven, moving through beautiful crunch tones until, at its
maximum position, a full distorted tone is arrived at.
13. Overdrive Volume
This controls the volume of the Overdrive Channel. Turning it clockwise increases
the volume.
Equalisation
14. Bass
The Bass control adjusts the amount of low-end frequencies in your tone. This amp
has an advanced tone shaping circuit which allows the tone to be tight and cutting,
counter clockwise, to warm and thumping, clockwise.
15. Middle
The Middle control adjusts the amount of middle frequencies in your tone. The middle
frequencies are particularly important in setting the amount of 'body' your tone has.
With the Middle control set to its minimum position (fully counter clockwise) the
sound will be aggressive and scooped, a tone ideal for aggressive rhythm playing.
As the Middle control is increased (clockwise) the amount of 'body' is increased,
which is more suitable for sustained lead guitar tones.
