Pictures of the build, which is the result of a complete lack of planning:

I didn't use a feedback loop. A guitar is enough to make it distort just slightly when playing hard, but does so in a crunchy kinda way (the point of using that particular input stage, it can't really hard-saturate).
I estimated 28W, and it sounds about that volume when maxed. The preamp is going to be a 4-stage Vulcan type circuit with 3-band + presence.
