Hello all, I believe this will work but I need advice from the experts here at TB. I would like to mod my Fender P/J so I can use a balance pot for pickup switching/blending. The question is, if I go to a Jazz Humbucker (SD, Fender Noiseless, etc.), will I experience any bad effects such as loss of gain, noise etc. I want to use a Humbucker because of noise on the standard J. This is a passive setup and I want to keep it that way, love the tone. Here is a schematic that I think will work: http://www.guitarelectronics.com/product/WDUSS2102 Thanks in advance!
