This pedal features all-discrete semiconductors, a dual-tone stack (two separate tone stacks, in series, one active and the other passive), three gain stages, and the user controls are Bass, Colour, Volume and a Gain switch. Of course it is wired for full-bypass switching. The lead guitar has Gain set to "hi" and rhythm guitar has it on "low" setting. If you look at the closeup photo at the beginning at 0:07 those are the knob settings I used on the lead guitar work.
By the way for you Strat lovers the rhythm guitar is on bridge pickup, and the lead varies between bridge pickup 0:53 , neck+middle pickup around 1:54 middle 2:15 and neck pickup 3:12 so you get the range of tones. I am using a 20 WATT AMP with 1, 12" speaker.
