CB-2P

CB-2P is an utility pedal that's not meant to work standalone, but to extend tonal range of vintage style fuzz pedals and let them handle buffered signal with ease.

Controls:
- pre-gain is a level attenuator (just like a vol knob in guitar)
- low frequency section is a bass attenuator at different frequencies selected by 6 position rotary switch
- XF switch selects guitar pickup simulation which helps low input impedance pedals like fuzz face, tone bender etc. work well and sound great after buffered devices. positions are off (toggle town), HB (humbucker, fatter/darker sound) or (single coil, sharper/brighter sound)
- there is also internal tone knob, which works just like tone knob in a guitar when pickup simulator is engaged

Whole circuit is passive, DC input is used only to power led.
