Re: Carr Amplifiers.......
What is your budget and what tones are you after?
Carr makes some nice stuff. I, however, found the Rambler to be a bit sterile if that is a decent amp term. The speaker probably hadn't broken in yet. Everyone raves about how good a blackface fender type amp it is.
I got to play a Carr Hamerhead at Ultrasound in NYC, but it was next to Brunos and Two Rocks and the like and it paled in comparison to everything else there.
I still believe, for my ears, the Two Rock stuff is the best on the planet. YMMV.
