Dropped off today for a service this very tidy looking Peavey Delta Blues combo. Potentiometers are noisy & the drive channel doesn’t appear to be working. Tremolo and reverb are working. Owner has replaced all tubes recently. #bridgnorthbusiness #shropshirebusiness #guitartech #amplifierrepair #audiorepair #audioservice #amprepair #peavey #peaveyamps #peaveyamplification #peaveydeltablues View this post on Facebook

It’s a lot of kit to fit in a standard size control cavity & strict rules for placement as the sustainer circuit will induce interference if the driver wiring is too close to the normal signal wiring. Had to replace the 5 way selector with […]

Current progress on the Charvel Sustainiac installation. The control cavity on this guitar with the default controls installed just wouldn’t give up enough space for the installation of the Sustainiac driver board, battery & additional toggle switches required for control of the sustainer system. The 5 way selector has had to be swapped out for […]
