From the vendor
Jon Patton's simple, transparent compressor circuit. Sitting neatly in the middle ground between ultra-subtle comps and super-skwishers.
There's a toggle to switch between long and short decay settings to suit your mood.
Warning - this one isn't keen on heavy playing dynamics. You will get distortion if you're mashing those strings.
Available with through-hole or SMT FET, so if you're confident with the fiddly soldering you can save a quid.
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 can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.
Inspired by: Torn's Peaker / US / Never Drive / Aenima
Difficulty: Easy
PCB size: 50 x 33mm
Knobs required: 2 (or 3)
Enclosure: 1590B
Direct Connect compatible (4-way)
