No offence ?,
I read this (
http://www.madeloud.com/articles/miscellaneous/does-he-build-best-guitar-amp-ever-legend-howard-alexander-dumble ) in which dumble seems to be a bit of a nutter, maybe rightly so:
"Dumble amps also have no deadline. It’s ready when it’s ready, and rumor has it you can’t call and bother him about when it’s going arrive or you lose your deposit (another version of the story is he would bump up your order further and take even more of his precious time building it if you annoy him).
Dumble has become an urban legend, like Bigfoot, and it isn’t easy to separate the facts of his story from the fiction. We’ve seen pictures of Dumble’s handiwork here and there, though if you put up pictures of the inside wiring of his amps online, he’ll ask you to remove them."
