The tube amps made and modified by the late Howard “Alexander” Dumble have become the stuff of quasi-Arthurian legend in guitar circles.
Kenny Wayne Shepherd swears by them. Joe Bonamassa regularly has them pumping up the volume in his amp shanty. That high-end superstar of all things six-strings and bougie, John Mayer, is a fan. In theory, we all are – at least, all of us who like the idea of a super-dynamic tube amp that’s probably too loud for the home and/or amateur use.
