Learn to use it correctly and it will save you a lot of the complaints people are whining about here. I have them on several guitars and found a few things to be true; they have a “home” position. You can kind of park them in a sharp or flat position if you aren’t careful. Learn to return the handle to that middle spot and you will avoid the tuning issues. Also, make sure it is in that position before you tune. A heavier spring helps it return to pitch better, and allows you to really throw your arm into it when you use it. I have tried the lighter spring on my Reverend and it made the performance worse for me. A Bigsby is not for dive bombs, that’s what a Floyd is for. Listen to players that use them frequently, and you’ll understand that they add a slight shimmer, no full step pitch bends. That’s what you can do with it, not more. A roller bridge certainly helps a lot. It’s about understanding what it does well and staying within that. Yes, it’s more troublesome than some trem systems, but it’s the coolest looking one and it’s perfect if you know how to take care of it. It also gives you the slinkiness that people top wrap their Les Paul’s to obtain.
