Hi! Many years ago (1988, I think), I've read the first test on a Music Man Silhouette: in the photograph of the guitar there was a tremolo bridge that took my attention... it was a non-floating locking bridge. It had the dimension of a vintage bridge, but with fine-tuning system, and there was also a locking nut... I would like to know what kind of bridge was it?!? Anybody can help me?
