The Mid control allows for 19dB of

9: HIGH: Adjust the high frequency
output level with this control: in the
center position the high frequency
output will be “flat” (no boost or cut).
Turning the control to the left reduces
the high frequency output; turning it to
the right increases the high frequency
output. The High control allows a total
range of 23dB of boost or cut at 5kHz.
10: REVERB: Adjust the amount of
Reverb effect with this control: in its
full-left position the signal will be “dry”
(without any reverb). As you turn the
control to the right the amount of
reverberation increases.
