From the vendor

Two transistor Muff Fuzz circuits in one box. Why not?

Toggle to the left and your output is from Muff No.1 alone. Toggle to the right and Muff No. 1's output feeds Muff No. 2, giving you twice the muff, which is likely 'nuff.

It actually works really well, since they each have their own volume control. Things can get mighty fuzzy with both cranked. There's life in the old circuit yet....

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.
