Good evening all. I have a ‘93 PRS Custom 22 with Dragon II pick ups and a stop tail piece. I bought it new at Chuck Levin’s and have cherished it ever since. But I’ve always wished it had a tremolo. I see there is a Schaller tremolo mechanism for about $200 which claims to adapt easily and fit perfectly onto any typical PRS, Gibson, etc. stop tailpiece. Has anyone had any luck or experience with these? Also, are there other options available? Or should I keep my guitar stock and look for another guitar that comes with a factory tremolo? Thanks and all the best.
