1 JBGretschGuy 5 months ago My buddy picked up a JTM45 chassis that had been cobbled, hacked, on fire, modified, desecrated, and generally forsaken for the last couple of decades. The tremolo circuit had been ripped out in favor of some kind of master volume circuit. It was hard to tell, because the amp was not in working condition. No one else seemed to want to restore order to this old girl to Clapton spec. After all, where you gonna get the tremolo board? The original RadioSpares De-Luxe output tranny? Phew.
