Hi Myles,
I have become very interested in Cornford amps since seeing your blurb on them on the "World's Best Amps" section of your website. Specifically, I am very interested the Carrera (and to a lesser extent the Harlequin - all thing being equal I would rather have reverb and an effects loop, not to mention the UniValve-esque ability to use various power tubes).
Unfortunately, there are no dealers anywhere near Phoenix, so I have been unable to try one out. What do you have to say about the Carrera and/or Harlequin (or Cornford amps in general)? Tone wise, can you compare/contrast them to other amps with 20 or fewer watts?
(My research has identified the Carmen Ghia, MAZ 18, MINI Z, UniValve, Kingsley Deluxe, and Vox CC-AC15 as other possibilities for my next amp, to be used for blues/rock - with an emphasis on good tones at moderate volumes)
