It's that time of that season where I get real fidgetty and start modifying my guitar so here's another question for you guys. This one concerns possible tremolo mechanisms for a non tremolo guitar such as les pauls that use stop bar tail pieces. I'm thinking of adding a tremolo mechanism to my les paul es. i wanted to add this "stetsbar" at first but i found out i cant replace the bridge on it with the piezo bridge i have so now i'm stuck with either choosing a les trem or a bowen handle. Anyone of you guys have tried any of these tremolo systems? How much tremolo can each give me (are they bi directional, do they both give a half a step?) and which one is better and stays more in tune- the bowen handle or the les trem. Also, anyone of you guys have tried those "rockinger les trem"- the one that Eddie Van Halen used in his guitars before the floydrose. Is the "rockinger les trem" better than the "les trem" they sell nowadays. Also, where can I buy a "rockinger les trem." I heard its one of those tremolo widely used in the 80's but suddenly disappeared from out of the blue when the floyd rose came out. Also, does anyone know if there's any bi directional tremolo out there available for les pauls besides the stetsbar.
