About this pre-amp business

a) The preamp is 1U. It has 3 knobs and 6 jacks.

b) It has 2 'line level' inputs with a gain of 0 to 10. It has 1 'guitar'
input with a gain of 0-150.

c) The pre-amp is for AC signals only. It is 'DC servo' driven, with no caps
in the audio path but has
auto-zeroing outputs. This is how all audiophile pre-amps are designed.

d) It uses a 'Larry bracket' mounting scheme: there is a thin stainless
steel bracket that is placed behind
the 3 pots.

e) No mic pre. That's too much a pain, and the sales volume would be small.
The MAIN use of the preamp is for
gee-tar players. The SECONDARY use is for boosting 1V pk-pk synth outputs to
10V pk-pk or so.

It is a straight preamp. No tone, overdrive, etc. I want something CHEAP and
EASY. But of course MOTM-type
specs (like 0.005% THD).

I hope to have at least a prototype for NAMM. Note that my 'real job' is
starting to pick up, so it remains to be seen just
how much I can design and ship in the next 3 months.

Well, that's good, since guitar players rule.
