Janglebox

A few people have asked for this.  It's pretty obvious what it's based on but I definitely think it's worth a build even if you already have a Dyna Comp or Keeley (etc) type compressor.  The tone switch does give you a lot of variation and I must say I was impressed by the demo vid.

Info about the original:

The original JangleBox compressor/sustainer is the pedal that captured the clean, bright ringing chime popularized by the Beatles, enhanced by the Byrds, and integrated into the sonic palettes of so many contemporary groups.

Ten years and thousands of satisfied customers later, there was no reason to reinvent the wheel, but we did add some subtle tweaks that make this unique pedal even better: a more stable IC chip, a more standardized power polarity and an enclosure that sits a bit closer to your pedal board.

Best of all, we brought the JangleBox home. Handmade in the USA once again, this simple plug-in/play compression pedal creates a bold sustain that will give your Ric, Tele, Gretsch, Strat — whatever the guitar — remarkable presence. Unlike pedals that clip or distort the original signal, the JangleBox expands the compression “sweet spot” to maintain a clean, even tone, with true bypass.

Compact and powerful, the JangleBox is ruggedly constructed for demanding pros and aspiring artists alike. Whether you’re looking to get that Beatles/Byrds chime and jangle, never-ending slide sustain, Nashville “squish,” or just a big, clean boost, the JangleBox delivers the distinctive compression edge.
