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.
