From the vendor

New for 2024 - make yourself an original Japanese design that is actually almost a straight-up clone of the Zen Drive - the Yogi variant below.

Dumble-in-a-Box? A mighty claim made by the designers of this boutique circuit. Decide for yourself it that's justified.

Smooth, medium-gain overdrive that will respond to your playing dynamics like it was sitting on your lap.

Debate around the innards of this pedal takes up a lot of interweb space, mainly on choice of op-amp and clipping diodes. Some originals used a AD712, some a common NE5532 - you can have either. You can try pretty much any 8-pin op-amp you like until you nail your perfect sound. Clipping is supplied as per original - 2N7000 FETs and BAT41 diodes.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.
