From the vendor

Old-school germanium fuzz tone machine from Burns (and don't forget Baldwin!).

This is a positive ground effect, which means much woe if you want to power it on the same daisy chain as your standard polarity pedals. But wait... this new version of the kit has an optional onboard voltage inverter, which means your power supply won't complain.

Very similar to a Tone Bender Mk III. Excellent sustain and very tweakable with the Balance and Timbre controls. This is the heaviest version of a Tone Bender type circuit these ears have come across.

The choice of transistors will grow as more experimentation and fiddling goes on at FDHQ. There's plenty of room on the board to take the meatiest of vintage cans. Right now we're supplying a combination of Russian MП16Б, MП41A and whatever others we have in stock, NOS Newmarket CV7007 (OC77), or you can have the kit without cans if you want to source your own.

The kit is supplied with vertical-mount pots which have round shafts, so you'll need set-screw fitting knobs.

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: Burns / Balwin Buzzaround

Difficulty: Easy

PCB size: 50 x 32mm

Knobs required: 3

Enclosure: 1590B
