A guitar has a vibrato, an amp has a tremolo. Sorry if I'm hijacking the thread but a real problem I have faced lately is the bend vibrato. I feel like every great guitar player I have ever heard has a beautiful bend vibrato. I have always done that by hand. Recently I found I can "cheat" with the Bigsby. Not sure why I'm asking but when should I do one over the other? It's a thing I struggle with.
