BlackHatSound – ColourSound Fuzz with Vintage Transistors and Bias Control

(1 customer review)


Point to Point Coloursound fuzz – This is a variation of my 183Sound Fuzz with an added external bias control. Built using super rare TO106 TUN ‘Blackhat’ transistors, producing a darker high octane fuzz with more grainy, vocal, on edge tone remenisent in tone of the Mk1 tonebender. Built using JB and Vischay capacitors, Cliffe jacks and alpha pots.

Available on back-order

Upgrade your suit lining with some metalic jazz!!



The filthy unruly brother of my 183sound. This special edition uses a matched pair of super rare vintage ‘New Old Stock’ TO106 cased, TUN ‘Blackhat’ transistors from the 1970s, turning the high octane 183Sound fuzz into a pedal that sounds  slightly darker, more grainy, scooped, and on edge. A small amount of Voltage sag on the front of the note and a very slightly gated finish. With echos of Neil Young buckling his Tweed Deluxe, spitty, saggy, huge and glorious, to the nasel Fuzztone in the intro to the Rolling Stones Satisfaction are  easy to dial in.

While it sounds killer with any guitar, however this circuit really lifts humbucker type guitars adding lots of pick attack and presence.

The bias control has a very smooth sweep and acts more like a contour or filter, until the last 20% where the tone starts to gate and break up, at this end you will find some very convincing FZ1 Fuzztones – especially with the bass cut activated.

I have a very limited stock of these transistors, when they are gone that’s it.

This pedal has chewy broken tone in the lower register, still keeping plenty of the huge bass these pedals are known for as you play further up the neck, the notes clear and get sweeter but still keep their ‘cut’ in the mix. It also cleans up fairly well from your guitars volume pot , however the note decay does finish slightly more gated. If you need to take out some bass there is an output cap switch that will limit the bass (a little), this pedal is also great to use with a bass guitar too, as the low frequency headroom is insane with the bass cut on full.

In all if you like your Fuzz messy and squelchy but still with plenty of tight bass this is the pedal for you.

Power Filtering Options

As standard my pedals are NOT fitted with a power filtering circuit, as per the original pedals they are based on. Noise in your signal can come from a very complex set of variable sources, so is very difficult to defend against. However I use a tried and tested power filter circuit. Fitting this may help remove ‘dirty power hum and hiss’ and some RF interference. If you are using a good quality power supply its probably not needed though. It can also be retrofitted.

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, theres 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 ecthing 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.

The grade and rating of every component has been painstakingly tested. I am proud to be able to say that this silicon fuzzface sounds as good as many GE versions but without the temperamental audio behavior.

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 germainium 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 controlers 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 resouces that can help. RF interference is not down to a faulty pedal.

    This things a beut! You could clear your bank account trying to find another mark one of this quality. And if you had to pay the price for that alternate you would. It has great attack and definition, nice distortion around the edges. And with the bass cut switch it really gets nice maestro tones except not thin and irritating like the original. And it passes the cave test. Put it through my custom vibrolux which has 10″ speakers and reduced negative feedback and it caved just enough to get “the sound” but still clean in the right frequency range to put the note through. So unless you’re railing out on a little Princeton or something you won’t have anything to worry about with this little wonder. But any amp with headroom and decent size speakers and you’re set for life.
