I have a TMG Dover. It is a Strat type guitar with a six screw trem Callaham aged bridge. I am not to the point of being able to use a trem to any benefit for me. When I do try and use it, everything goes out of tune. I know I can lube the nut slots and it should be okay, but I really have no use for it at the moment. What is the best way to block a trem that is quickly and easily reversible as my skills get better? My newbieness may be showing. I have seen where some have put wood under the rear but I would like a more exact method. Maybe a tremol-no? Or would something like a thin metal plate along the lines of the neck plate, but sized to fit work?
