Well, if nobody's truly going I suppose I'll take a whack.
Around 2000 I got a bass on trade from my pal Glenn. Lovely old Czech bass with a label of "Alois Bittner" from the early 20th. The bass was in many pieces and Glenn, a bass-player who ran a piano-repair shop, promised to put it back together. And he did, but it fell apart again. So Glenn said he'd "really fix it" and boy, he did. And it was a nice sounding bass -- quite the cannon for its modest size.
Fast forward about five years. There's now some buzzy things happening so I brought the bass to the Uptons. And they deeply regret to inform me that Glenn had "really fixed" the Bittner by gluing everything together with EPOXY. The bass may buzz a bit but it could probably float across a pond without sinking.
I decided to invest the effort in having the Uptons remove all the epoxy and restore the bass properly. Their photo-essay is
here. Uncounted blades were ground down by that goop, friends. But at the end, the bass was in one piece and sounding better than ever.
Post-script: I ran into Glenn some months later. "How about that epoxy?" I sez. He looked a little sheepish, then he said, "Give it up! How many good years did you get out of that thing anyway?" That was the end of our last conversation.
