Think of the controls as three separate sections:
1. Gain (RED)
The gain structure is made up of three parts:
–The Pre Volume (labeled "Pre-Vol") can be used the same as you would a Drive knob on an overdrive pedal. In this circuit, the Pre Volume is between the two gain stages, and the setting of the Pre Volume determines how much signal continues to the second stage.
–The Master Gain (labeled "Master") is what would typically be considered as a Volume control. Other terms are "master volume" or the "output trim."
–The Step Gain (labeled "Step") changes the gain of each preamp stage in five stages. Rotating the "Step" knob from left-to-right will increase the gain by the following:
1 is X 18 db
2 is X 23 db
3 is X 28 db
4 is X 33 db
5 is X 39 db
2. Equalizer / Tone Control (BLUE)
The tone control section is a highly modified Baxandall type that is tuned for less control interaction and more boost/cut capability. The center frequencies are Treble 10kHz, Middle 1kHz, and Bass 120Hz, with +/- 17dB of control.
3. Highpass Filter (YELLOW)
The Highpass spans from 60Hz to 800Hz with a 6dB per octave slope. This control allows you to only let high frequencies pass. In return you will find a vast palet of tones that sit perfect and inspire textures that you have never heard from your rig. The toggle switch will turn the Highpass on or off.
