Controls the amount of amplification or attenuation applied to the filter.
A large knob with twenty-one positions. The lowest and highest settings are as follows:
Positions within 3dB of unity gain are in increments of 0.5dB above and below this are 1dB increments.
Note: To facilitate A/B comparisons of a band's effect, double-clicking on the control resets its value to zero, acting as a band bypass.
A second double-click restores the control to its previous setting.
