I suggested to Mark he cut the grooves deeper to accept O-rings, I bought some but they were too thick. For me, I have no issues with slippage, but on my particular Tele, it's flat out wide open all the time. He redesigned the shape (no piston) and a few modders went nuts for it. He also made me some heavily knurled flat top knobs for my Esquire which work well for the volume swell thing. O-ring knobs...
No slipping, luckily there was no oil left on 'em from the little motorcycle they came out of :burnout:
I can't wait until the bike is done, that is going to be total sickness! First thing I thought when it was all together was I better learn how to play really fast now!
