Mr. Black BB-74x

This is Jack Deville's Marshall-in-a-box emulating a 1974X 18-watt combo amp. Tracing credit goes to Ralf Gottschalk, who has a nice little dual-layer board of this up on OshPark if you don't feel like etching or grabbing the perf for this one (build doc with schematic in the description).

Jack Deville Deuce Coupe

Here's a modified version of the Deuce Coupe. It's an opamp based drive with a charge pump so the circuit runs off +/-9v. The originals have relay bypass switching and a boost function (that I've not included in this layout). You can probably fit it in a 1590B, but a 125B will be a little roomier.

Jack Deville Boost Tiger

Here's an op-amp based boost circuit from Jack Deville (Mr. Black Effects). He was kind enough to share his schematic a couple years ago on FSB. I stumbled upon it and thought it would be a good addition here. It should easily fit in a 1590a, and you can probably board mount the pot too.

Jack Deville Vintage Two-Knob Fuzz

I've been wanting to do a Fuzz Face with on-board pots for a while, and when I stumbled across a schematic of Jack Deville's (Mr. Black) take on the classic circuit, things just fell into place. This uses NPN germanium transistors (though you could use silicons if you must), and I tried to leave plenty of room for them if you're using some of the big Russian germaniums easily available off eBay (GT404, MP38, etc). You could build a standard Fuzz Face on this board, just mind the component changes and replace the resistor from Fuzz 1 to ground with a jumper.

Update 5/4/15:

Verified this last night. Here's a pic of my build.

Used some Russian мп38 germanium transistors (Q1: 80 hfe Q2: 110 hfe) and a 7.5k resistor in place of the 10k trimmer (ran out of those). For the input cap I tried out a couple different values (47n, 100n, 220n...) but settled on 39n, as it seemed to give more clarity that higher values. Socket and experiment.
