GAIN – Dual gang pot controls the gain of the op-amps in tandem.
VOLUME - Works as expected, with plenty on tap.
TONE - Think of the tone knob as a blend between a low bandwidth and a high one. At noon, they
are equal. To the left blends more lows and to the right blends more highs.
MIDS - Adds the low mids to the mix. Fully CCW and the tone knob is quite scooped. Fully CW and a good amount of lower mids are added to the mix. Works in tandem with the tone knob.
TOGGLE– Changes clipping options for the second op-amp. North is hard clipped red LED. Middle is soft clipped Zener, and south is hard clipped silicon.
Internal Trim - Adjusts the bias of the JFET. We do not recommend touching this unless you have experience with a digital multi-meter.
