Have spent the day trying to fix a) this bloody pc, and b) a strange problem on my Rickenbacker 12 string. Regarding point b). Anyone familiar with RIC wiring??? I recently had a problem with the p/up selector switch of my 1966 450/12 (a non-electrical problem: the toggle wasn't staying in the up or down position) which I fixed I have reassembled the Ric, only to discover the volume output from the treble pickup was normal, but the neck (bass) pickup is maxxing out at about half the volume of the other. I can find no faults in the wiring circuit - after testing with a multi meter. But here’s the weirdness…… the lead p/up is reading 6.76kOhms on the meter, but the one at the neck reads Zero! Despite the fact that I can hear output from it… Any thoughts on the matter? A suspect “ground” somewhere? Or is the old toaster top pickup simply shagged out? I appreciate that this could be a number of things, so all ideas / help / suggestions welcome.
