Here’s a great tip on how to help keep those guitars in tune that have a Bigsby & a Tune-o-matic bridge. The strings can sometimes get hung up in the saddles and this easy mod can really help. I would not do this mod to an original vintage ABR-1 however. Get a good replacement if you have a vintage instrument. Please feel free to contact me with any questions…….I’m serious, email me I will help if I can!!!
