Sean,
The only amp I recall with user adjustable feedback is the Mesa Baron. I believe it is adjustable between 0 and 8db in 4 increments.
This is an amp I am considering purchasing, btw. It is a very flexible (can also switch between all triode and all pentode in 1/3 increments) dual mono amp and may be what I need in order to determine what works best with my ESLs (other than OTLs of course).
Kevin Hayes has also offered to make some mods to a PA100 for me which is another option.
Thanks.
Mike
