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.
D*A*M SONIC TITAN - VERO LAYOUT
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.

The 4.7uf cap going from the gate to ground should be going from source to ground instead. Same on all the layouts. Cheers
thanks - updated. that would have sounded interesting
From experience with building a few of these, the LM386N-4 works best in my opinion. Less artifacts on note decay. I can only imagine it's maybe something to do with voltage headroom vs the N-3?
I also like the cap on Pin 4 replaced with a 4.7nf or 10nF and 100k Level Pot, I put a 10nF and 220nF cap on a DPDT On-On switch. The 220nF gives a great sludgy sound for stoner riffs.
Also shielded cable is a must in my opinion or you're in helicopter land without a buffer in front.
