Hi all! I finally got my L-1000 conversion completed by my luthier just before closing time on Saturday on my way to a gig. He got it done just in time for that gig, but we didn't have time to work out any of the bugs. We only did a super quick test through a tiny guitar amp (that's all he had handy at the moment) and I suspected that the treble control wasn't doing much. I got to the gig and through my big rig, it was super obvious that yeah, the treble does nothing and seems to be all the way off (I compared with my L2000 to match tone). Heck, luckily it was a Country gig, so a little extra dark wasn't a deal breaker and I used it all night anyway. Still sounded pretty awesome! Anyway, he's going to try to figure what went wrong but he's closed until tomorrow, so in the meantime, if anyone has an ideas what's gone wrong.. This circuit is completely new to him also
His wiring looks super cleanly done (although some of the pots are facing a different direction from many of the old body cavity shots floating around). Following and matching 5 or 6 different old circuit pics and the attached diagram (the white wire from the pickup is missing on this diagram, but it's meant to go to the switch where the other white wire is), it looks like he got everything right that I can see (other than a few arbitrary different coloured wires - but they seem to go to the right places). I don't see any obvious broken connections or shorts.
Any ideas what might be amiss? Could it just be a bad pot or something?
Another related question, some of the other block diagrams I've seen show a resistor on the treble control and have the connections to different terminals, yet I haven't seen photographic evidence of a real example of this. All of the pics I've seen floating around here have no resistor and are wired up just like mine. Even Paul Gagnon's schematic show the resistor, yet I've not seen it on any actual pics.
