Default Adjustable internal Resonance?

The direct interaction of tubes and components has a resonating effect on the signal.
Harmonics can be tightened or released to create an acoustic instrument-like natural resonance.

The language is obscure, he talks guru language, I really don't understand what he's talking about, do you?

Anyway his amplifier looks funny, that's why I'm posting this...the text is also funny.

Do this only if you feel bored, be warned:

Bah, I don't understand his technical descriptions but he makes nice guitars, so he is forgiven.

Still, if someone knows about the resonant control I'd like to know.

I glanced over the site and didn't see a detailed description. However, it's not very mysterious. I guess he's simply using the natural microphonic behaviour of DHT filament tubes to mechanically resonate with the output. Not that much different from a spring reverb. I guess that he "adjusts" it by changing the amount of dampining between amp and speaker output.

MI designers and manufacturers live in a different world where it is about making music rather than reproducing it. The amplifier and speaker is a big part of that combination. Hyperbole seems to be the norm, possibly there is some reasonably solid engineering underneath it all, but few musicians I know care much about that - it's all about seeking the holy grail of tone..

First I thought it could be a feedback control with tone adjustment, but what Sheldon says sounds much more interesting, even though I don't understand how he can control the microphonics to make it musical. So yeah, language is obscure and technique unknown so I guess I will never know.

My guess is that it is just a conventional "body" control all hyped up.

This line is a bad start:

No capacitors or resistors are in the way, as with conventional tube amplifier designs.

With this one starts the fun:

The input absorbs all the unique character of the introduced signal.

It doesn't melt my brain, I'm having fun:

The signal flows freely without distortion or limitations in frequency range

...but he makes fine guitars. He won't go to hell.

May be he speaks language of his customers?

Also, if we ask him, may be he speak our language as well?
