The Bigsby installation was very simple, once I'd lined it up with some string to make sure it was centre, I only had to drill a few pilot holes to mount it. The neck feels silk to the touch, and I think the satin gives it a nice vintage vibe that I'd have never achieved with play-wear alone on that plastic finish. After roughly 2-3 hours of this, I used T-Cut automotive scratch remover on a lint free cloth to bring the guitar back to the level of shine that I desired.
After removing all hardware, I used a mesh attachment to an orbital sander (you can do it by hand with a scouring pad, but the random nature of the sander's movements reduces the swirl pattern and makes polishing easier) and made sure to get a good, even coverage to reduce any shiny spots. The process was very simple, and I'd done it before to an Epiphone SG. I recently impulse bought a Bigsby B7 for my Casino Coupe, and while installing it I decided to take the gloss finish down to a more satin feel, as I'm not really a fan of the candy-like polyurethane finish that comes from the factory.
