Thanks! Yes this one is about 10.5 lbs. I am considering that, maybe with a Vibramate mounting plate that keeps it reversible. Since I have a Gretsch with a Bigsby, I just might leave this one a hard tail.
That's the route I went, too. Easy install, works like a champ. It's been on there so long now I kinda forget the Vibramate's even there.
Of course, it's a B7, so not quite as buttery smooth as a B3/B6, but it's plenty workable. I'm happy with it!
