Do any of you have experience with playing, installing, or having a b-bender installed in a Les Paul Jr.? I have a great sounding Les Paul Jr. that I would love to have equiped with a bender. It has a brass adjustable zero fret nut and the traditional wrap around bridge. I've seen Juniors with a bender before, but I wonder if anyone has direct experience with one--who installed it, did it stay in tune, did the wrap around bridge rock too much, etc.? It's a little heavy too--probably around 8lbs--is that going to pull it out of tune too easily? Thanks guys.
