From the vendor
Nice crunch box based almost entirely on a Rat with a few tweaks.
External pot for 'Shape', i.e. the Ruez mod which is very popular on Rat builds. Asymetrical LED clipping gives it a harder edge than a standard Rat.
There's a toggle switch to engage a feedback loop from output back to input, which can be a lot of fun or complete waste of time depending on your outlook. We like that kind of thing around here.
This is based on the Mk I of the original pedal, which is entirely different to the later Mk II, so if you're looking for that one keep searching.
The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs. You also have the option to replace the stock linear Gain pot with a reverse log, which gives much more control.
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 and vertical-mount pots. Please choose appropriate knobs.
Inspired by: Wave Cannon Mk I
Difficulty: Medium
PCB size: 50 x 40mm
Knobs required: 4
Enclosure: 1590B
Direct-Connect compatible (4-way)
