Jerry probably wouldn't agree with a 60yr old PU, thinking they went dead after a while, side note...why didn't anyone save all his used PUs? I think they would be fairly sought after. But for once I will disagree with Jerry (don't hurt me), Pus don't go bad (IMO). Post a recording when you break out the Gibson, I'd love to hear it.
I still have an old brass slide (had it since I was a teenager), may have to check out the ceramic... but I still sound worse than Bobby with one so I may have to get that sorted first
