Moon Unit - Dark Side of the Fuzz

Silly name. Serious fuzz.

Nail the classic tone of Dave G's solo from "Time", with all the tweaking you could possibly desire across five knobs.

As well as the obvious Volume and Fuzz pots this box also gives you:

  • Body - how much bass you're pushing into the circuit - has a huge bearing on the nature of the fuzz rather than just the frequency range
  • Brite - as it says, brighten up the tone. Huge range from dark and murky to brilliant
  • Range - choose how much gain you want the first fuzzy transistor to have, which has a knock-on effect on the rest of the circuit.

    It's a beast, but it can also be a pussycat with the right settings.

    Designed for vertical board-mounted pots which have round shafts, so you'll need knobs that fix with a set screw. Spacing is tight (18.5mm apart), so you'll need small knobs.

    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 only available 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.

    Difficulty: Medium

    PCB size: 50 x 36mm

    Knobs required: 5

    Enclosure: 1590B

    Give in to the Dark Side of the Moon 5 product stars
    "'s an animal! Built within a couple of hours, pretty simple even for beginners and as usual everything you need is included. The knobs are very responsive and the effect can produce a wide variety of tones, indeed from mild fuzz to gilmourish distorted tones. I changed the Q1 to a BC108C to "restrain" the overall aggression, it sounded better to my gear / taste, you can try it as well and keep whichever transistor you like the most. Turn the body all way up and octave harmonics shows up (not too much, but definitely audible!). It works well with wah and booster / overdrives before it, as well with booster and effects after it. If do not crank up everything to 11 it is also quite "quiet" for a fuzz!!! Enjoy!!!!" Dimitrios Kligkopoulos - 01/09/2018
    Dark and fuzzy, with just a hint of moon... 4 product stars
    "Interesting fuzz with lots of tonal controls. The body and bright controls have a good range, and being able to control the bass and treble independently makes dialling in the tone you want much easier. Not as much gain on tap as you might expect, so if you're looking for a heavily saturated tone then this is probably not the fuzz for you. What it does have is chiming upper mid range bite, making it perfect for giving your solos an edge to cut through the mix and add sustain whilst still retaining all of your playing dynamics. It's also good at lower gain settings as a slightly fuzzy overdrive, which sounds great pushing lower gain amps to add more in the way of saturation. My only real gripe is that unity gain is very high (just shy of full volume), which is a bit of a shame. The build was pretty straight forward (only the 2nd build I'd ever done), instructions were very easy to read." Ben Miles - 12/06/2016
