1 Jimmyguitar 7 months ago Hi everyone, i’m new here! I just bought a beautiful 1965 Gretsch Duo Jet but the Burns trem unit had cracks in it. Turns out it was incorrectly positioned at the factory and the front screw went straight into the cavity thus offering zero support for the string tension. Seeing as anything I do to remedy this will ultimately make this guitar a ‘players’ piece I want to fit an old gold Bigsby. A friend has a B6 from the 60’s but everyone says a B3 is what should be fitted.Will a B6 fit? It seems to me that the closer the string anchor is to the bridge the better?I’ve found a pic of a 50’s duo jet with what appears to be a B6 and it looks fine to me.Thanks!
