howdy... 1st: not too long ago i took my '81 L1000 fretless in to have the fingerboard sanded, the original pickup put back in, and a general setup. when i got my bass back i noticed that on the tiny bit of the fingerboard on the HEADSTOCK side of the nut there were deep grooves filed into the fingerboard underneath the E, A, and D strings. I asked the repairman about this, and he said he had to do that to get the action low enough (the nut slots were cut almost right down to the fingerboard.) he assured me this was a perfectly normal procedure. i've had fretlessess set up a few times, as well as nuts cut, and no one ever did that. anyone ever heard of this? one person i spoke with at a guitar shop said he probably just filed too far when he was filing the nut. 2nd: the bridge pole piece for the G string on the original pickup (slot style pole pieces) in my bass sounds distinctly duller and has less volume than the other pole pieces, even when i have it raised all the way up! does anyone know if this sounds like a wiring problem, or something else (maybe the magnet is just old)? i'm thinking about putting the newer pickup i ordered from G&L a few years ago back in. it doesn't fit in the cavity as snugly (it's smaller)--does that make a difference (if there's a little space around the pickup)?
