From the vendor

Box of magical optical wobbles.

Lots of different tremolo tunings to be had. Normal controls you'd expect - Speed, Intensity and Volume - are enhanced with the Slope control. Smooth sine through to squarewave stuttering.

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 enclosures and vertical-mount pots. Please choose appropriate knobs.

Inspired by: Voodoo Lab Tremolo

Difficulty: Medium

PCB size: 50 x 45mm
