In response to an earlier post referring to the Tremol-no... no disrespect (disre-no) I had used one of these in a project Jackson Soloist I was building. There were too many adjustments and the little screws kept coming loose on their own. You could also hear the piston sliding when you did a dive through your amp!
Granted, I use some pretty high-gain, modded amps with a hot signal, but it just didn't seem optimal to me. Sometimes simple is still best. Love the wood block idea :)
