A variation of one of the greatest and gnarliest fuzz pedals of all time: made in Japan by Shin-ei/Unicord - the same circuit as the Shaftesbury Duo Fuzz.

The name is really irrelevant - Super Fuzz or Duo Fuzz - the sound is what counts: it's basically two very different shades of monstrous filth - ripping chainsaw fuzz or brutal octave-ish wildness.

 This pedal is in excellent working order & very good cosmetic condition for a pedal dating from the early-mid 70s (see detailed photos). 


Notable musicians who have used the Super-Fuzz include:

Pete Townshend of The Who

Billy Cox of Jimi Hendrix

Kurt Cobain of Nirvana (Stolen in 1989 during the Bleach recording sessions. He mainly used the BOSS DS-1 and DS-2 afterward.)

Josh Homme of Them Crooked Vultures, Queens of the Stone Age and Kyuss

Hillel Slovak of Red Hot Chili Peppers

Dan Auerbach of The Black Keys uses the Ibanez Standard Fuzz, a nearly identical circuit in an altered housing.

Mark Arm and Steve Turner of Mudhoney

J Mascis of Dinosaur Jr.

Billy Corgan of Smashing Pumpkins (Although he was much more famous for using the Fender Blender and the Electro-Harmonix Big Muff)

Adam Yauch of Beastie Boys

Jus Oborn of Electric Wizard

Poison Ivy of The Cramps

Joe Preston of Thrones

Scott Hill of Fu Manchu

Tony McPhee of The Groundhogs

Chris Walla of Death Cab for Cutie

Elliott Frazier of Ringo Deathstarr

Gary Louris of The Jayhawks

Joe Denardo of Growing

Wil Smith of Utah


This pedal is in good working order - no crackly pots or noisy switch issues.

(Please note: it is always possible with vintage equipment that some crackly pots/sliders may develop over time when equipment has not been used - even during shipping - this can usually be easily rectified either by use or with a bit of switch-cleaning spray).


Fitted with a battery and ready to play.


Tax (VAT)

Some of our gear will have VAT at 20% added in the UK/EU, but a lot of it won't. This should hopefully clarify the situation but if you have any questions then please get in touch.


  • These items will have two prices visible: with and without the tax.
  • If you are buying in the UK/EU you will receive an invoice showing the tax component.
  • If you are buying these items outside the EU when you get to the check out and enter your shipping location you will be charged the ex-VAT price.
  • VAT-free sales are also possible to businesses within the EU with a valid VAT number. You will need to contact us in order to buy via this means.


    • Much of what we sell is classified as "Second Hand Goods" and so while we still pay some tax, there is no recoverable/deductible component for sales to any part of the world.
    • So, the price you see is the price you pay wherever you are.


    • Shipping charges are also subject to VAT at 20% within the UK/EU - this is included within the prices you see for shipping to those areas - it is not shown separately in the cart but will be shown on the VAT invoice you receive with your goods.

    WE OFFER FREE SHIPPING TO THE UK! There are some exclusions for distant areas and islands (see below), and also some occasional exclusions for very large/heavy/valuable items which will be clearly noted in the item descriptions.


    • You will need a bespoke shipping quote!
    • Our shipping calculator on here won't give you the right figure (and may well not give you one at all).
    • Please get in touch via the contact page and we can give an accurate shipping figure for multiple items.
    • If it is outside office hours and you are concerned about missing a piece of gear then buy it at the quoted shipping rate, send us a message saying what else it is you want to add, and we will deal with the discount once we are back on email.
    • You can do this with absolute confidence that we will give you a full refund if the final shipping quote is doesn't work for you.


    We are very experienced at packing and shipping valuable and sensitive gear worldwide - Binson Echorecs, large valve amps, vintage synths - you name it, we've sent it and it's arrived in one piece. Obviously from time to time with vintage items there are times when gear arrives in need of some adjustment or calibration, and some times a piece of gear that was working 100% just chooses the day after arriving for a new fault to develop - however, we are also very experienced at dealing with these occurences and will always work with you to solve the problem

    The shipping prices for our gear vary considerably depending on the type of gear, value and destination. Currently the only way for you to see shipping is to put the item you are interested in the cart and then either use the shipping estimator or go into the check out process. Or just contact us and we'll tell you what you need to know.

    Also note that we have have not entered automatic shipping for every country. The countries we ship to most often will have shipping rates and we are in the process of adding more shipping fees to the check out process. But if you are looking at an item that doesn't have the fee information you need then please use the contact page or call on 07543 855788.

    If you are considering a purchase and want to check you have our best rate then please always contact us direct and we will give you an exact figure.

    Also note that for some items we are able to discount shipping to North America - continental USA and Canada. The fees you see at check out will take this discount into account. But if you have a question... you know what to do.


    We use Royal Mail, UPS and DPD/Interlink - it depends on the item and destination as to which is the most economical. If you have a preference then we should be able to accommodate it (but we may need to pass on any additional costs).


    We are not able to ship free to some of the UK islands (e.g. Channel Islands) and also to some of the further reaches of Scotland. If you think you might be in one of those area and want an accurate shipping quote before you buy then please get in touch.

    There are also some items which we cannot offer free shipping on to the UK. These will be clearly noted in the description.
