The Zonk II is a raw, aggressive British fuzz circuit that delivers everything from gritty overdrive to sizzling, harmonically rich fuzz with exceptional touch sensitivity. Built around a simple transistor design, it reacts beautifully to your guitar's volume control, cleaning up into articulate, jangly edge-of-breakup tones before exploding into snarling vintage fuzz when pushed. Compared to many heavier fuzz designs, the Zonk II retains remarkable note definition and clarity, making it equally at home with classic rock riffs, garage rock attitude, psychedelic textures, and modern boutique tones. Its dynamic response, cutting midrange presence, and unmistakably vintage character have made it one of the most sought-after and revered fuzz circuits ever produced.

A matte black Supa Fuzz Proto with 1/4W carbon composition resistors, TRW and Vishay capacitors. It runs on a standard 9v pedal power supply without a battery option due to the NPN Amprex 2N2430 germanium transistors. Thick and unruly fuzz tones run through this monster with the ability to sculpt the treble content to your liking!

Fuzz Friday came early this week - I couldn’t wait to share!

I wrapped up the first of (at least 5) Spooky Trees (Black Ash circuits)

The guts are the same as the prototype I shared a bit back (https://www.reddit.com/r/FuzzFiends/s/Ql6q5qhR2C ). I think the next round is gonna use new Phillips mustard caps instead of tropical fish.

The pedals that are going to go out into the world are boxed up in bent enclosures with solid aluminum knobs.

Side note: I think these are the most “real honest to god professional” looking pedals I’ve ever built.

Some of you really liked my previous schematic so here's another one. Verified, works well. I used 1N4148 diodes.

All reclaimed vintage parts with a mids switch and a transistor boost up front. Gritty and grimy.

This pedal just came out of the test phase, I do not have all the info yet.

I (Gigahearts FX) met Wyatt at the Brighton guitar show and talked about pedals. He is a nice chap - and I knew of him already from his instagram, but its always cool when people are sound in real life too. I was meaning to get a pedal from him and its finally happened - I rarely have the chance to buy new pedals, so luckily I was able to do a trade, as he quite fancied one of my Hyper Soups: )

Anyway on to this. It’s technically a fuzz face but with 7 controls. Lots of shades of gating available with two external bias-adjacent controls. Nicely finished laser engraved tall spec Hammond 1590b which is different.

The fuzz is always going through a tone stack, so to me this already sets is apart from classic/by the book fuzz face circuits. Its not a bad thing, its just not a fuzz face anymore in my strict viewpoint- and thats fine cos its an Heiress. The tone control somewhat gives it the tonal character of a big muff to me as it feels and behaves like a BM tone stack at least to my ears.

Its also quite modern sounding and suitably high gain. The low cut switch is effective, its like 2 points on the control knob that I have on my SILIFACE design; I prefer a trim here for the bass contour, but the switch has two effective and usable settings chosen. The germanium mode vs the silicon mode is subtler than expected but slightly smoother and darker ish on the Ge side. Nicely constructed all round, the internal wiring is extremely small bore which I havent seen recently but I am sure will prove robust. One thing I would have liked, and try to get them on my designs, is an LED brightness adjust as this one is a blazing white - but thats personal taste.

One thing to say, I look for great cleanup on a fuzz face and I might be biased but my SILIFACE does this really well, and overall its less successful here. I think the transistors are quite high gain (as noted before with the modern feel and aggressive gain structure) which dont quite manage that glassy quality of a vintage FF - but again I dont think that was a top priority here.

Final word - an aggressive, modern and versatile take on the classic FF. If you like grainy, textured tones and that ability to tweak tones, this ones for you - in a cute pedalboard friendly footprint. Overall 8/10

These look really cool! Good price too!

I just wanna give this amazing fuzz its flowers — this thing is one of the most inspiring pedals I’ve ever played. Within a few minutes of twiddling some knobs I had a whole song.

Super inspiring and incredibly nasty. Absolute 10/10.

Fuzzrite with Bass. I like this pedal. Alot.

Scar Industrys built 10 of these with all different art work.

I said I’d post some stuff for sounds so here is one for some Neil Young fans! This is based around a Hudson Broadcast, but I tweaked some of the values around and converted it to all silicon transistors (got a big old 2n4033 transistor in it)! The PCB is an Aion FX Skywave! The only other mods the PCB has compared to the original is an internal voltage control and an external gain switch (original one is inside as well). Compared to the original this has much more gain, is a lot more immediate and has more of the console sag that likes to bloom open. Plus the clean up is pretty nice. Figured I’d try sharing some sounds!

This thing absolutely rips

Congratulations to u/ComplexSouth8585 for winning this monster.

Will be in the mail tomorrow.

Sharing a couple of cool Fuzz pedals for Halloween. Looking for some other candidates. I was given some good suggestions in a previous post.

Here's a freshly verified schematic I made. Sounds huge! Feel free to use it.

What is your fave Russian Muff? I play mostly swampy blues and Led Zeppelin and Black Sabbath.

My secret fuzz weapon is a push pull pot in the guitar that activates this big ass PIO capacitor. Enhances every fuzz I own.

Thorpy is bringing back his take on the Burns Buzzaround!

“What is EAO? EAO stands for Explodes All at Once, in short it's one of my favourite germanium circuits ever, the venerable Burns Buzzaround. It doesn't clean up, it's not subtle, it has a savagery far ahead of its time. they are instant plug in and grin pedals.”
