i bought some low price Bigsby copies for no good reason. I really hate them after having them on two guitars that I hated. I hate the word hate because it too strong and people that use it have no clue what true hate is. I put the first vibrate or tremolo on my Les Paul Junior, that a guitar I never liked. It went on way to easy, I used a laser diode to set the lines for the E strings on the fret board and nut. Drill, install strings and a bit of a set up. The damn thing works and a bone nut helps it stay in tune. I'm very proud of me for screwing in my first Bigsby ever. I have two more to go and one vintage Japanese tremolo.
