: I've got a 1980 Kimbara Jazz copy. It sounds pretty muffled now and short of going to a technician I'd like to get it usable as a spare.
: Is it likely to just be the tone controls dying or could the pickups be going? The pickups have a non-standard mounting - a single screw at the top and bottom instead of a true J pickup mounting. Is it possible to just replace the pickup inside the cover?
: I'm very competent with a soldering iron but not so hot on fault finding. Any tips on diagnosing the problems would be great (I have a digital multimeter but no access to an oscilloscope).
Actually, one of the first things I'd do would be to boil the strings to clean any dirt and crud off of them; I had a little short-scale bass, and the first time I boiled the strings, the difference was like night and day!
If the sound is still muffled, you might want to change the capacitors on the tone pots; some types can dry out as time goes by, so it's not a bad idea to just replace them. After that, I'd probably get some contact cleaner and shoot some in all of the pots and any switches, just to clean things up.
Pickups would probably be most likely to develop a break in the coil (which would break the circuit), if anything; it's possible, though, that the pickup magnets might be weak, which would mean that they'd need re-magnetizing.
Not sure if that solves your problem, but I hope it helps!
