From the vendor
Clone your own Deep Blue Delay. What's that? It's a PT2399-based digital delay with an analog direct signal path. It's a nice, natural-sounding delay with the warmth of a vintage tape echo. First repeat is clean, subsequent repeats start to darken and degrade. A great alternative to more clinical devices - this has soul Three controls: Mix, Delay, Feedback. Keeping it real! Or keep it unreal by adding a fourth pot for 'dirt', which adds an adjustable audio feedback path in the delay signal for added filth, oscillations and runaway feeback. Delay time is between 25 - 450ms. Feedback is from 1 to infinite with darkening and self-oscillation. 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.
