Negative feedback, transformers? Ummm, no thanks. I'll stick with my BK Butler designed and built TDB-5150. BK's designs are revolutionary and the build quality is superb.

Hardly a fair comparison when the Butlers cost over 2-1/2 times as much as the Bob Carvers.
The Butler is no doubt a stupendous design. His guitar pedal effects are legendary and I have a friend who used to work for him and holds his abilities in awe.
Still, that doesn't mean Carver's new tube amps should be dismissed because they have user-selectable feedback levels, which are probably relatively low (especially the 11dB setting) compared to many amps.
