One Knob Fuzz

Such a lot of thick fuzz for such a small build. Excellent response to playing dynamics. Now available in several boutique variations. Thug configuration requires a transistor leg twist - sorry!

The circuit has a board-mounted pot for minimal wiring and simple enclosure mounting.

Kit is available with a standard sized 1590B enclosure with battery, or a mini 1590A (36 x 90mm) enclosure with DC power only, though be aware that you'll be wiring in a very confined space.

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 (1590B) / will not (1590A) take a battery. Knobs are not included.

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

Difficulty: Easy

PCB size: 32 x 22mm

Knobs required: 1

Enclosure: 1590B, 1590A

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.

First Build (in which a noob gains basic skills) 5 product stars
"I picked this for my first build. For anyone else doing the same let me tell you silly mistakes! With the standard daughterboard for the footswitch, the switch goes on the reverse of the PCB as does the LED. If you're a noob like me, make sure you have desoldering braid on hand! You cant solder one handed. You need a third hand/solder station type thing. Sure, transistors are sensitive to heat. But if you're trying to de-solder some funky joint you just botched, its super easy to melt plastic wire shielding and indeed other plastic things like the power terminal! Do a little bit at a time because your ability to problem solve and solder sucks after a couple of hours. Choose the bigger enclosure for your first build, I went for the little one which was fiddly to do straight off the bat. Check your solder joints the next day, if they look bad they probably are. A multimeter helped, I found reading 5 band resistor codes confusing RE orientation. Wrote down both possibilities, confirmed with MM. Despite all these learning points, I now have a working an gnarly fuzz. The character varies as the knob goes up. It's gonna be good for cutting leads. The kit actually missed some hook-up wire for the jacks and power but I had my own, no biggie. I ordered a couple more kits and they all look correct - really looking forward to building them."

Colorsound OKF & FuzzBlood 5 product stars
"Really nice and dirty fuzzes. The Coloursound is a bit more classic sounding. The Bloodfuzz is simply brutal and rude. Fully cranked it can almost sound like a square wave. Rolling down your guitar volume works really well to get a more old-school fuzz sound (when your guitar has two volume knobs you can go form slightly fuzzy to full on fuzz by just flipping the pickup selector switch). The customer support is really great. Any question I had was answered within a few hours." Bas Hermus - 14/09/2018
Ceremony and Colorsound 5 product stars
"Another good addition to anyones collection. I have tried a couple of these, Ceremony is very heavy and works well with detuned guitars but is not a delicate fuzz by any means. The Coloursound one got very muddy on the 6th string but lowering the value of C4 brought back the definition and lowered the gain a bit. A very usable classic sound." MrG - 30/08/2018
An absolute monster 5 product stars
"Best fuzz I've ever heard. Thick, weighty and dirty as hell. I've built a few kits from fuzzdog and the quality and customer service have always been great. If you like fuzz, but find the muff too scooped and the fuzzface too tinny, buy this. Fairly easy to fit into a 1590a enclosure too, totally recommended" crm - 23/07/2015
Wicked fuzz, great build 5 product stars
"My first build, easy to do. I am sort of a well informed novice. Gooched the power a couple of times but my trusty multimeter showed me the path of righteousness. Nice fuzz sound, heavy distorted, frying egg sputter, love it." ThickShag - 28/01/2014
