Hey thanks for the feedback. I had my local luthier/ tech do the work while it was in for a re-fret. It's a 22 so the middle pickup worked with a standar Dimarzio ring. In fact I bought three so they would match. I hated the PRS treble pickup hence the bare knuckles PAF. The neck PU is still a stock PRS bass Dragon II. It's quite sweet so I kept it.
There is also a wald buffer on board but that may have happened after that gig. I can't really recall.
Probally a blend at the 4 minute mark but also hard to recall. That's a vintage BOSS turbo OD just like Jerry had. I love it and still use it with my axe fx. Guys on the internet swear by the OD1. I've got one. The turbo is better.
I think I bought my Turbo new in the early 80s, but can't recall that either. Could have come from a pawn shop. I never use the turbo option, and doubt Jerry did as well.
