TriVibe

RunOffGroove rarely disappoint, and this modulation box is no exception.

Seeing a lack of DIY projects for true vibrato they set out to fill that gap, and a fine job they made of it too, using readily available components that don't require any fiddly matching, biasing, fairy dust or hammers to get working. The project page linked above is well worth a read.

Two simple controls - Rate and Depth. Three modes - Vibe (take a guess!), Swirl (mild two-stage phasing) and Whirl (somewhere in between, rotary speaker-ish), should give you enough variation to make the fairly large build worthwhile.

We've managed to keep the whole thing withing a 5cm square PCB so it'll easily fit into a 1590B enclosure. There are six resistors on the back side of the board to achieve this footprint, but why not eh?

There's also an optional rate indicator LED for those of you who like flashy things.


Kit includes: PCB, all components, hook-up wire, 3PDT footswitch for true bypass, high quality jack sockets, DC socket, battery snap, LED. Enclosure (pre-drilled) is optional and will not take a battery. Does not include knobs.

Difficulty: Medium

PCB size: 50 x 50mm

Knobs required: 2

Enclosure: 1590B

Direct-Connect compatible (4-way)


If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability. Builds only available with vertical-mount pots.
