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 pads so you can easily add the mids-scoop pot mod.

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 only available with full kits, and will take a battery. Knobs are not included.

Builds are only available with full kits including enclosures. Please choose appropriate knobs.

Difficulty: Medium

PCB size: 50 x 22mm

Knobs required: 2 (3 with mids scoop pot)

Enclosure: 1590B

Direct-Connect compatible (4-way)

"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
