I have several bigsbys....including my '58 gretsch. If you have a roller bridge and a proper sized nut (I prefer bone)...the thing does stay in tune. It is NOT a dive bomber and you can pull up (tight) on the strings enough to stretch them out of tune. You can get a nice wavy tone from a bar chord...like kicking in a vintage fender (amp) tremolo (with out the click).
I have a b6, b5 and b16 and the Gretsch.
