I wasn't joking about the Twin Reverb well a Princeton works well too. Try to get dirty at low volumes and you wind up with the kind of tone I hate. Mushy, all blended together, distorted junk. If the goal is to be a better guitar player then an amp that lets you hear every string, every note, the way you pick every note and yes every mistake is the way to do it. Just my opinion and not a very popular one I know.
