circuit diagnostic
A beastly Ibanez 5 string bass in for an intermittent short circuit and fret buzz. I traced the output issue to a bad 25k volume pot that needed to be replaced (see video below for the replacement). As for the fret buzz, treble side fret ends 12-20 were playing it high and loose. The inexpensive fix was to glue and clamp them back down. Doing a fret level after they were locked back down would have further improved clean playing up the neck.
1968 Vox Grand Prix [8.5 lbs] :: quick solder fix.
I had this in the shop two years ago for an overhaul. You can get more details of the Electronic Odyssey project here.
The guitar was in recently due to an intermittent battery issue. Note this guitar has multiple onboard effects that require 9V power to pass signal, even when bypassed (see above link for details). One of the battery lead splices was shorting out and had to be stripped back, soldered and shrink wrapped. Back in business.
