This fuzz is my homage to the John Hornby Skewes MK2 ZONK MACHINE. Using my own tweaked version of the original Mk2 two transistor silicon Zonk circuit. Using a matched pair of super rare vintage 'New Old Stock' TO98 Sprague 2n2926 Gold Dot silicon transistors from the late 1960s

A mid gain super textured fuzz with octave overtones.

    • SWELL control (volume)
    • DRIFT control that mimics how old component values in original units may have 'drifted' up or down over the decades since they were made. This control acts a little like a fuzz and a little like a bias and give a wide range of really usable settings . Max isn't the only option here!
    • TEXTURE This is a pot to control the texture of the fuzz, it adds even more graininess - this reduces sustain and the note crackle, especially effecting the decay adding a much more 'crumbly' nature and more artefacts as the pot is turned anti clockwise.

Built using a very sort after vintage silicon transistors, and high spec new components. Built using JB and Vishay capacitors, Lumburg jacks and alpha pots.

AHHH Silicon ... I hear all the Ge nerds muttering. I can honestly say that with carefully chosen and measured components the actual differences between Si and Ge in this circuit are much more subtle than you would believe. Have a listen to the demo and see for your self...

I build these fuzz pedals in my garden workshop in Northamptonshire UK. This includes painting, drilling, and acid etching my design onto the enclosures. Constructing the entire circuit ‘Point to Point’ only using the components, there's no boards or circuit traces to dilute your signal purity. I finish the entire pedal to a standard that I think looks as good inside, as it sounds on the outside. It might be covered up but when you’re in that moment you KNOW the mojo you have under the hood.

Please be aware, these are totally hand built and so there might me some slight cosmetic variation between each pedal. The acid etching process produces a gunmetal patina on the enclosure with will vary from pedal to pedal. This is most noticeable on the sides and imparts a unique character to each pedal. Tonally, I play each one to make sure they sound as good as the first one, before signing off, no tone generator, no gadgets – just a telecaster and my ears.

Please note, all my silicon pedals have a boss style 2.1 center negative DC jack only, there is no battery snap. Silicon transistors are not sensitive to DC supply type unlike their germanium counterparts.

Thank you for reading, if you have any questions about this pedal feel free to message me.

RF interference - Many old fuzz circuits are vunerable to Radio Frequency Interference from a host of different modern electronic devices ranging from lighting to heating controllers to fridges. This is by the nature of the design and to reduce the chances of this happening would radically alter how the pedal sounds. If you are having problems with RF using one of my pedals here are a few resources that can help. RF interference is not down to a faulty pedal.

Actually Cooling Pillow
Size: Queen (1 Count), Color: Original White (Cooling)
This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!

Repurchased in King Size – Still Love These Cooling Pillows
Size: King (2 Count), Color: Original White (Cooling), Size: King (2 Count), Color: Original White (Cooling)
After using the queen-size version of these pillows for over a year, we purchased the king-size set when we upgraded to a king mattress. Both my husband and I really like them. The cooling feature works well, and we like that each side feels different—when I run cold, I use the softer bamboo side, while my husband prefers the cooler side since he tends to sleep hot. They fit well in our king-size pillowcases and feel supportive in all sleeping positions, whether I’m on my stomach, side, or back. I also appreciate that you can remove some of the filling to adjust the firmness. The covers are washable, which makes them easy to maintain. Overall, we’re very happy with this repurchase and the long-lasting comfort.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.
