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.
