Anyone out there care to help me with a measurement? I was given a prtotype Tokiwa tremolo bridge about 35 years ago for my Epiphone Olymipic. I had deleted the stock trem and was using the stop tail bridge only, and had just replaced it with a now unobtainable Schaler piece. Unfortunately the spacing on my posts is narrower than the Tokiwa spacing. Of course, I hung on to it..I think it will fit an SG, and I was considering making a gift of it. It's really nice, you can lock the trem out if you want, and it has individual saddles for setting the intonation properly. Just need to check the center to center on the posts to see if it matches.
