For some insight as to how & why Carr Amplifiers are superior, we've certainly come to appreciate that Steve and his crew are indeed guitarists!  Here's a brief introduction from their website:

"Like you, all of us at Carr Amplifiers are guitarists. We share your love of the guitar, and we feel very fortunate to build amplifiers for a living at our shop in Pittsboro, North Carolina. And although we are understandably proud of our unique circuit designs, meticulous point-to-point construction, premium components and hand-crafted cabinets, our success has ultimately been the result of one simple fact; discerning guitarists continue to enthusiastically embrace the tone, reliability and versatile nature of our amplifiers. Perhaps it's because we view guitar amps as being as much an instrument as the guitar itself, and we truly believe that an amplifier should become a personal extension of every player. To that end, we strive to design and build amps with a distinct character and sonic personality, and the flexibility and practical features that will inspire you to create your very own signature sound at volume levels appropriate for home, studio and stage.

We sincerely appreciate your interest in Carr Amplifiers, and as you review the models described here, we invite you to contact us personally to assist you in choosing the best Carr amp for your needs."

With best wishes,
Steve Carr, Founder
