Ilitch electronics BPNCS adjusting PCB PUBLIC

Tracing of a Ilitch Electronics BPNCS noise cancelling system for a strat-style guitar adjusting PCB. http://www.ilitchelectronics.com/strat-bpncs/

My own tracing of adjusting PCB of ilitch BPNCS noise cancelling system. I'm going to rebuilt it, as I'm not happy with lack of any mounting system on it. PCB number is "32111r4" -- it seems, like this PCB is used for several different style of their noise systems, so some of the pads are not used. It's unclear for me why C3 cap is there -- it's connected only to the metallized hole and pad -- both of them not connected to anything else. Probably it's there for testing purpose, but not really sure. I'm going to omit it my own version.
