From the vendor

The original transistor-based version of the EHX Muff Fuzz.

A completely different beast to the later op-amp version. Worth a punt if you're after some classic dirt from a tiny circuit.

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, in a 1590B. 1590A will not take a battery. Knobs are not included.

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

Inspired by: EHX Muff Fuzz

Difficulty: Easy

PCB size: 30 x 20mm

Knobs required: 1

Enclosure: 1590B/span>

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.
