Check out the tremolo at site listed below, that thing looks sort of cool. I like the fact that you can use a quarter to change the strings, cause after a while the allen screw heads and wrenches start to round off

I've been wondering for a long time why someone hasn't done away with the
allen wrenches. I remember that Jackson made a floyd version
lock nut with the flat head screws that you could use a nickle or quarter to lock/unlock. Does anyone know if anyone makes locknut screws like that. I would buy em.
