From the vendor

Always room for one more tape echo type fun. PT2399-based delay with lo-fi repeats of 30-600ms and some sweet wobbly modulation to emulate wow and flutter. Controls are: • Time - Delay length • Repeats - slapback to oscillating foreverness • Mix - Dry/wet control • Depth - How wobbly do you want it? Just a little shimmy or walking home after 12 pints. • Shape - Smooth triangle CCW, transforming into full-on square wave chop as you spin CW. • Rate - Fast or slow wobbling. The board has been designed for 3mm resistors. Beware - these are tiny, fiddly and the codes are difficult to read, though the neat results are worth the effort. We can supply 6mm resistors if you're happy to stand them upright on the PCB. The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. We recommend 1900H knobs as the pot spacing is a tight 17.5mm. 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. Please choose appropriate knobs. Inspired by: Space Spiral Difficulty: Medium-Hard PCB size: 54 x 59mm Knobs required: 6 (Small!)
