Didn't make any entries until I resolved that last post, which was to start designing and building the next step, the 30 watt.
I built one, sent it to a famous pickup maker, and we both decided we didn't like the result.
He owns a 7 watt and loves it.
So I got it back and stripped out to start over.
In the meantime I was able to do a similar build into a Fender 75 chassis, with channel switching via a couple of XLR cables.
Passive, but quiet.
The gain channel sounded great so that became the springboard for the next portotype, then the Orpheus built into the same chassis as the 7 watt.

We'll see.

I think it sounds awesome.
