BlackHatSound – Vintage Fuzz with NOS Transistors and Bias Control

(4 customer reviews)


Out of stock



Point to Point Vintage 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 (‘Tonebender’ is a trademark of Solosound Ltd -they are also awesome) . Built using JB and Vishay capacitors, Lumberg jacks and alpha pots.

All parts are played through the BlackHatSound at different setting shown in the top right corner of the screen

This unique fuzz uses a matched pair of super rare vintage ‘New Old Stock’ TO106 cased, TUN ‘Blackhat’ transistors from the 1970s, creating a pedal that sounds full, musical and full of force. Its a very pick sensitive fuzz, letting your guitars charactar show through, there are many usable tones when dialing back the guitars volume control. There is also thunderous bass available with the bass switch in the up position and the tone has enough mids to be heard in the mix, but not to many to sound muddy. The bias control can go from smooth and flowing Gilmor tones, though voltage sag on the front of the note and a gated finish, think Neil Young buckling his Tweed Deluxe, spitty, saggy, huge and glorious, to the nasel Fuzztone in the intro to the Rolling Stones Satisfaction.

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

Clip will play from the point the pedal is featured.

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.


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.

    The guys at That Pedal Show are right; this thing has a special feel to it. There’s a ton of volume on tap but I’m not a super loud player, so I was a little worried that my Princeton set at 3 just wouldn’t do the Black Hat Sounds justice.
    I may not be tapping it’s full potential but I can report there are glorious sounds aplenty at low volume.
    Sweeping the bias knob took me from gated spitty knarley tones all the way up to full singing lead lines. A slide will bring out incredible definition and some really beautiful tones. But there are a lot of different and useable sounds across the entire range of that bias.
    Of course the build quality is just stunning. True art in a box. Everything from the visual design and etch work to the point-to-point wiring is done by Mr. Reeves and it is worth the price of admission on it’s own. The sound feels like something living and breathing under your fingers and I truly connect with it.

    Beauty and the beast! Beauty staring up at me from the etched design, and full on beast mode when you step in it.
    It’s hard to believe that such a stunning work of art can overwhelm the rest of my pedals so much, but it does just that.
    If you’re looking for ‘one to rule all’ this is the weapon.

    What an absolute monster tone!

    Most people can’t help but comment when they see the beautifully detailed and pristine guts of all of the Reeves pedals and (purely aesthetically) they are sublime. The level of craftsmanship and care inside is verging on the ridiculous.. but that’s not what these pedals are about.

    The BlackHatSound has got to be one of the meatiest silicon fuzz pedals out there. It certainly dwarfed the two highly regarded (and expensive) ones I had in my collection before*. The tone is perfectly balanced. There’s real weight to the sound but without losing the snarling mids and crispy top end. If you’ve got a bass heavy rig or want to leave some sonic space for your bassist then the bass reduction switch is also really well balanced. It reduces the bass without leaving a thin or anaemic compromised sound.

    So, yes.. I’m a fan! Thank you Marcus for creating such an instant classic.

    * I like those pedal builders too much to name names 😉
