@zulu Thank you!! I had figured it is probably not so difficult. However my local luthier will only follow a diagram. I am guessing your caps on the tone pots are .022?
2 Things have occured to me as a result of this thread.
#1, the original circut for those EMG's in this bass is not simply "2 vols and 2 tones." At least one of the knobs is a boost, and possibly a second one is a filter. EMG does not appear to offer that original circut, now. The current EMG designs include pickup switches, and/or other variants. But I was not really going for the EMG's.
#2, I am realizing a back up plan is to wire it like a Fender Jazz bass. Then just one knob on the Guild would do nothing. But I will try the Zulu diagram. cheers!
