I recently got a chance to try out a Telecaster with the "Dark Circuit" wiring and I loved it. (especially with OD) But it made me want that feature in my guitars. The ideas I had for it were to either: A. Add a 5 position rotary switch in place of my pickup selector and have positions 2 and 4 feature the dark circuit for one pickup or the other or B. I could use a push\pull pot for the volume (or tone...not sure which) and get the effect that way. What would be the best option? And is there something im not getting?
