Thought I might add the Wampler Plexi-Drive to the list after I did another Benson layout, as they are similar in many ways. Just look at the two schematics side by side, and you'll see what I mean.
Like anything involving JFETS, choose the resistors going to the drains to suit your JEFTS; they can and often do vary. Usually, aiming for half voltage on the drain is an excellent place to start; this is where a breadboard and some clips come in handy.

WAMPLER PLEXI-DRIVE - SCHEMATIC & LTSPICE RESULTS
note: LTspice doesn't have a regular switch in the library, so I've used a 100meg resistor in place of the "open" switch setting, and a 1ohm resistor for "closed".

Marvelous! Everybody loves plexi！Wampler Plexi Drive and Ramble FX Marvel are my most used and favorite Pedal。
Thanks Ding. I’ll have to check out the Marvel as well. Looks interesting.
