Welcome to TGP (fellow Philly guy here as well). Which amp do you currently own?
I have been a mesa guy since the mid 80s and love them. The only amp that I really didn't care for was the rectifier series. I never played a single but I've played duals and triples. They do that rectifier tone very well if that is what you're looking for. I thought it to be kind of one-dimensional. I also own a 5150 which I think is more versatile than the rec series. They can be a little noisy.
