FuzzPup EA Trem

This is part of our FuzzPup range of circuits designed for 1590A builds. They're not especially difficult, but working in a confined space can be fiddly. Take heed.

Of course there's nothing stopping you using these PCBs for 'standard' builds. They're Direct Connect compatible.

A different PCB is available for 'standard' 1590B builds - see the related products listed below.

Fairly simple but nicely effective tremolo kit.

A lot of trems use expensive optocouplers or require some fiddling with LED/LDR combinations to make them work, but this does all the magic with a clever combination of transistors.

The kit is supplied with MLCC caps for the 470n/1u parts. There's plenty of space on the PCB for film caps, but these will likely be too tall to get the finished board into the box.

Rate, Depth and Volume controls

Comes with a separate daughterboard to easily mount the pots to the main PCB.

Pots have round shafts so you'll need set-screw fitting knobs. Pot spacing is 18mm.

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 daughterboard, jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and will not take a battery. Knobs are not included.

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

Supplied with 9mm pots (round shaft)
