Ummm, can't that be better accomplished by simply changing the spring tension to pull the unit all the way back in its cavity?cheers for the feedback on experience. i am thinking tremol-no is not the best option really. thinking abou a dive-only tremolo blocker alternative.
Furthermore, it baffles me why people would get a guitar with a vibrato (which is actually what these things do) bar, and then prevent its use. If sustain and pure tone are the objective, why not buy a guitar that has a stop or tune-o-matic type fixed bridge?
