From the vendor

Great little chorus designed by Frequency Central. Note: The reviewer shown below must have had issues with his build as when put together correctly this is a very nice effect. This board is based on the Birthday edition, which includes MicTester's original anti-lock mod to stop the PT2399 sticking. It's also possible to include Jack Orman's NYE anti-lock mod with a few component changes. Optional toggles for Vibe and Space Warble mods (which will be credited as soon as we can dig back and see who came up with them!). After some experimentation we've found a 100KC pot is better for the Depth control than the original 500KC. You can have either - up to you. 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. Inspired by: Little Angel Chorus Difficulty: Medium PCB size: 50 x 50mm Knobs required: 2 Enclosure: 1590B Direct-Connect compatible (4-way) Download the INSTRUCTION PDF
