Shin-Ei FY2 Companion Fuzz with post-boost

Really skanky vintage fuzz tones. Fizzy, splattery, over-the-top and gloriously nasty.

The original circuit has a less than earthshattering output level, so this version has an added LPB post-boost to make everything go up to eleven.

New version of the PCB has board-mounted pots for even easier build and convenient enclosure mounting.

Includes a couple of pads so you can easily add the mids-scoop pot mod.

Caution: the component spacing is very tight and the pads are a little smaller than most of the other FuzzDog PCBs. It was necessary to get everything into this board-mounted pot format. No big soldering iron tips allowed!

Kit includes: PCB, all components, hook-up wire, 3PDT footswitch for true bypass, jack sockets, DC socket, battery snap, LED. Enclosure (pre-drilled) is optional and will take a battery. Does not include knobs.

Difficulty: Medium

PCB size: 50 x 22mm

Knobs required: 2 (3 with mids scoop pot)

Enclosure: 1590B

Direct-Connect compatible (4-way)

If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability.

"This is great. It arrived -like usual- so quickly I was a bit surprised. Had it built in about three hours including my dinner and five cups of tea. It sounds brilliant, like a drunk guitarist knocking the s# t out of a wasps nest with a de-restricted moped. I love it. Hopefully a reverb next. Thanks man!" Mick - 30/01/2016
