I'm redoing the rather shoddy wiring job that the previous owner did on my converted-to P/J squier. I ordered the new pickguard, and don't really have any desire to add a third knob and have to drill a hole in the new pickguard. I was planning on using a stacked volume/volume pot to a tone pot, but I can't find any stacked pots that have the same values. They're all 250k+500k. Can anyone point me in the right direction?
