This Rickenbacker came into the shop having had its bridge replaced with a later adjustable bridge, a rough replacement pickguard installed, and the wiring altered. The original tailpiece had been cut down to accept the new bridge but by a stroke of luck there was a bridge from 1965 420 for sale on Ebay. Fitting the bridge required redrilling a recess in the body which had been filed previously. The tricky part was cutting a pickguard to match the original. The shape and controls were a close match for the original but the cutouts for pickup and bridge had to be carefully reconstructed.
