Apart from the vital<br />
valve tone this ingenious<br />
power amp design provides, it<br />
also allows us to replicate various<br />
“circuit characteristics”<br />
that are unique to the all-valve<br />
power stages of the amps<br />
we’ve modelled. These “characteristics”<br />
include: Class A or<br />
Class AB operation, Presence<br />
and Resonance (low end)<br />
control circuitry (both found in<br />
the negative feedback circuit<br />
that some, but not all, valve<br />
power amps have). Being able<br />

to match such vital characteristics helps ensure that each and every one of our<br />
models is as tonally authentic as possible - as opposed to the usual “close but definitely<br />
no cigar” norm of digital modeling. And just so you know, this patented in<br />
USA power amp technology is unique to VOX Valvetronix.<br />
