Okay. So I'd like to get a bigsby for my Oscar Schmidt oe30. I copped one for a great price and had some work done on it and threw in new humbuckers. I'd now like to put a bigsby on there, and my question is which model bigsby is the one to get? I've tried researching the different models (b70, b50, b30, etc.) but I can't seem to figure out which is the correct one. Any help would be greatly appreciated!
