D*A*M: Sonic Titan ST-07

This is as close as I could get to the original layout for the D*A*M Sonic Titan.   It's pretty much a JFET smashing the LM386 with level, but in the nicest possible way.  I've read a 10k level pot can brighten things up a little. Apparently, this was on some of the earlier versions.  

There's also a bit of discussion around how the tone control functions and interacts with the level control, resulting in the third layout below, using the Sonic Samurai mods.  Other issues include DC causing crackle down the line (no cap on the input to the FET) and 386 note decay issues.

This slightly alternative version is closer to the photos I can find and is also part of the discussion on freestompboxes.

The original used a 2N3819 JFET - I've listed a J201 as it's the same pinout as some other common FETs, and I have a few and like the sound.

Notice any similarities between the layout above and the circuit from the datasheet below? David Main from, or who is D*A*M, mentioned that the Sonic Titan is a couple of circuits jammed together.  One is straight frodatasheet sheet, and the other is a standard JFET boost.
