Ya, I've been second guessing my desire to get a Bassman the last little while. In the store, it sounds great cuz it's clean, but at gigging volume, or garage band volume, it would break up, which is not what I want.
So, I'm looking at a Twin alot, and liking what I'm hearing. It sounded great in the store, a bit fuller, which I liked. Again, hard to tell at "store volume" but it was nice. I haven't been able to play a Custom 15 yet, so I guess I'll have to go to Steve's Music where I'm sure they'll have it.
Keep the suggestions and help coming.
