Zen Drive Project – Bodhi

Back in the day, the Zen Drive from Hermida Audio  was a super-hot, super-hyped, super-loved boutique overdrive pedal. It was on everyone’s board, from P&W church bands to post-rock hippie ensembles. Many said it was magical and unlike any other drive pedal; some said it was “just a Tubescreamer with big price tag”. Turns out they were both wrong. It’s actually a semi-original drive circuit, starting off like a Tubescreamer but ditching the famous “mid-hump” tone control and opting instead for a simpler buffered passive tone (high) cut, as well as adding the “Voice” control that adjusts frequency gain in the first op amp stage. Cool, I suppose. If you’re into that kind of thing.

So I figured I’d rustle up my own Zen Drive PCB layout. I made this one way back in the days when doing so would get you branded as a “pirate” or “thief” or even “terrorist.” Hyperbole is a crutch for the callow and unimaginative carnival barkers of society. 🙂

This layout has offboard wiring of everything, which makes it suitable for the DIY who doesn’t want to be constrained by precise drill layouts. I updated the artwork in 2023, but the original layout dates from 2012.
