It doesn't appear to be based on anything I'm familiar with, that of course doesn't mean it's not.
It looks like a very simple circuit, I'm expecting something similar to the limiter circuit in the Fulltone 2B / FDIC.
What's on the workbench?

You mean the Ge diode circuit? I never thought of that as a "limiter" the effect is so subtle on the FDIC. Still it's a cool boost pedal.

Yep, Fulltone calls it the "2B Boost with Limiter" . I'm assuming the 10K resistor (R5) + Dynamics pot prevent any significant clipping and softly reduces gain with stronger signals.
There's not a heck of a lot going on in this one.

I'm going to have to dig out my FDIC and mess with it again.

nn simple comp?

Might be a FET based comp. Those two pads have something on the back I think.
Robert

Yep, there are two on the back.
Yep.

Nope, you had it right the first time, it's the NN Simple Comp.

I just finished making a wooden enclosure for my tube preamp, using some birch hardwood with very nice figure in it.
At home, I feed my guitar into this preamp (with effects before & after), and then into a low-power class-D amp, and finally into some smaller moderate efficiency speakers. That way I can play at reasonable volumes (I'm old and deaf enough already), and still enjoy a great sound. But just like it's fun to dress up my stompboxes, it seemed appropriate to make something nice for my preamp.

How do you like the preamp? What’s it voiced like?

I'm definitely not as amp-aware as you and many others clearly are, so it's frankly a challenge for me to properly describe its voice with confidence - my apologies for that. It's the Frenzel FM-DP1 which is a 12AX-7 tubed preamp with a Fender 3-band tone stack and 2 inputs, one more clean/Fender-ish and the other more aggressive/Marshall-like (with separate gain controls). I just received it, so I'm still very much playing around with it. To my ears, the preamp seems pretty flexible, and it definitely can provide good tube warmth as well as gainier rock attitude. But give me some more time with it + finish getting it properly integrated into my setup, and then I'll try to capture some sounds and post them. [My original amp is a THD Univalve, which definitely can provide bucketloads of attitude - I run NOS 6K6-GT's in it for indoor-friendly volumes, and it can really growl.]

That was a typo, the ad copy was supposed to read it's "quite a superb cold-compress".
That's some tasty joinery there and the control panel POPS! Love the black face with white Davies 1500-esque knobs.

And yes, I f'ed up and put my post on the wrong thread, I realized it almost immediately afterwards. Sincerely oops.

@darwin999 Hey, we're all human. It was a running gag for me is all — but, now I wish I'd kept my yap shut. I think the running gag has run its course.
I do love the joinery, that's some thick, tight fingers. Beautiful amp.
My cheap shot denigrated the sincerity of my complement, which wasn't my intention.
Okay, better to shut up and be thought a fool than to open my mouth and remove all doubt. I'm going to shut up now.
SO, sincerely OOPS on MY part.
