2023-GPX-Secret-Weapon-Fuzzes-700.jpg

A reader asked me to pick out some of my all-time favourite fuzzes - which are legion actually - just far too many to include in a single rundown. So we settled on doing somewhat less well known favourite fuzzes - under the guise of ’Secret Weapon Fuzzes’. These are mostly somewhat under the radar classics - several of which are discontinued, but all of which deliver distinct superior tones.

 

Beyond these being Secret Weapon Fuzzes there was no other specific theme - so we get a variety of different sizes, and actually a really decent spread of different fuzz genres - with a number of totally killer super versatile multi-fuzzes.

 

I was aiming for around 20, but it made sense to draw the line at 16 - partly from the visual jigsaw and symmetry, and partly from the variety of textures and styles already covered.

 

Here is that very special list :

  • Anasounds Crankled Bitoun Octave Fuzz (Fuzz Face > Super Fuzz) - discontinued - €249 (c$270) when new
  • Bardic Audio Devices 2 Stroke Beaver (Opamp Muff) - $220
  • Bispell Audio Gleam MKII Fuzz (Silicon Multi-Fuzz) - £159.99 (c$205)
  • Blakemore Effects Deus Ex Machina (Opamp Muff) - discontinued - $149 when new
  • Dr Scientist BitQuest (Modulated Opamp Fuzz) - $249
  • Drunk Beaver Drunk Beaver Fluff Fuzz + Octave + Boost (Enhanced Muff) - $150
  • El Músico Loco Wee Beaver Fuzz Small (Regulus VIII) - discontinued - $160 when new
  • Fjord Fuzz Gjallarhorn V4 (Super Fuzz) - discontinued - $150 when new
  • Free Fall Diver Huge (Muff Fuzz) - discontinued - ¥23,000 (c$160) when new
  • Kuro Custo Audio Akuma Fiery Fuzz - €169 (c$185)
  • Paul Trombetta Bone Machine GTX - discontinued - c$300 when new
  • ProAnalog Devices MKIV Vintage - discontinued - $299 when new
  • Rainger FX DFST-1 Stealth Mini (Chop Fuzz) - discontinued - £229 (c$290) when new
  • Redbeard Effects Honey Badger Sub-Octave Fuzz - £219.99 ($280)
  • Shift Line Termofuzz (multi-fuzz) - discontinued - $165 when new
  • Toneczar Vault (Super Fuzz) - $395

I own all of those bar the Blakemore Effects Deus Ex Machina Fuzz - which I’m currently desperately trying to revive. This is third time’s the charm for the Deus Ex Machina - where I’m definitely now going to contact Blake Hickey - possibly later today, possibly Monday - that pedal just perfectly completes this picture.

 

As you can read from the legends half of these are currently discontinued - while Oleg at Shift Line is currently hard at work on a new version of his legendary Termofuzz - so hopefully that should materialise in the next month or few. As for many of those other discontinued ones they are kind of nigh impossible to pick up nowadays - you need to be very patient and then pounce like a falcon if you ever spot one. If took me several years to track down some of those - and several of those rarities were of course second-hand!

 

Here follow the individual details :


Anasounds Crankled Bitoun Octave Fuzz (Fuzz Face > Super Fuzz) - discontinued - €249 (c$270) when new

close

Controls - Volume, Tone, Buzz (Fuzz Face Gain), Fuzz (Super Fuzz Gain), INTERNAL } Bias, Ring Freq (Modulation), Feed (Input Gain), LED Brightness.

 

Probably still my favourite Octave Fuzz to date - this is a pretty unique double-fuzz which loads an expressive silicon Fuzz Face / Anasounds Feed Me Fuzz into a fantastically textured Super Fuzz - producing a fantastic thick and richly textured octave style fuzz - with some cool controls. Essentially this is the limited / special edition of the Bitoun Fuzz - with 4 external controls in place of the usual 2 - just makes it more versatile to deploy. Those different editions are set up somewhat differently with the Crankled one typically with a much more extreme gated bias - while I tune it back for ultimate thickness and texture. I think only 50 of these were made at the time - this one regularly makes a return to the board - and when I want some full-on Octave Fuzz action - this is usually my first choice. Note that the Toneczar Vault occupies similar territory to a degree while I perceive that one slightly differently - more high gain and searing really!


Bardic Audio Devices 2 Stroke Beaver (Opamp Muff) - $220

close

Controls - Level, Clipping x 8, Sustain, 5-Band Graphic EQ, Clean Blend Control, Left Engage Footswitch, Right HM-2 EQ Footswitch.

 

This is pretty much my first recommendation for Opamp Muff - where the hybrid KMA Machines Chief Disruptor is a close second - but obviously in far higher circulation - so that one doesn't qualify for less well known status. There's really not that many 2 Stroke Beavers around - which are also branded as 'Shelob's Lair' it's the exact same circuit - and per my edition it was original called the 2 Stroke Beaver. You get 5-Band EQ here along with Clean Blend - and the ability to shape the output to the most extreme or nuanced degree - really sounds superb!


Bispell Audio Gleam MKII Fuzz (Silicon Multi-Fuzz) - £159.99 (c$205)

close

Controls - Bass, Mid Cut, Treble, Volume, Bias, Gain, Impedance : MKI / FZ-1 / MKII + FF, Tone : FF / MKI + FZ-1 / MKII

 

This recently reviewed multi-fuzz is a monster of its kind - covering off so many of those early classic fuzz types with 4 superbly well selected and calibrated Silicon Transistors. Thomas has properly tweaked it to new levels of refinement in this V2 edition - really takes you different places - and of course allows you to go far beyond those classics if you want to - to deliver your own style of searing or subtle fuzz. This one really should be selling by the bucketload - still really well priced too!


Blakemore Effects Deus Ex Machina (Opamp Muff) - discontinued - $149 when new

close

Controls - Volume, Gain, Tone, Clean Blend, Mid Boost.

 

And onto my big white whale of the moment - which I'm still eagerly trying to revive - both on behalf of classic fuzz fans and the Shoegaze crowd which exclusively uses this pedal with Reverb pushing its front - so the clean blend is essential. I and more traditional i.e. non-shoegazers just love its mid-pushed combination of Brian May Solo tones and MKIII Tone Bender - just a brilliant sounding unique fuzz that was cut off in its prime and evaded the notice of most everyone - including me at the time. Along with Bob Guido - I've been trying to vigourlously uncover one of these - and get it back into production in some guise - with Blake Hickey in some way onboard - even if just to give his blessing and nominate a favoured builder to carry out that task. I've been privy to a couple of new fuzzes which get into similar territory - but are slightly different, and don't have the clean blend. I feel this one is special enough to deserve another run or few! Please add your support to the campaign!


Dr Scientist BitQuest (Modulated Opamp Fuzz) - $249

close

Controls - Patch : Flanger / HP+LP Filters / Bit Crusher / Reverb / Notch Filter / Ring Mod / Pitch Shift / Delay, Mode : Dirty / Clean, Ctrl1, Ctrl2, Tone, Gain / Ctril0, Volume, Mix.

 

Readers will know that this one's sibling - the Frazz Dazzler is one of my all time favourite fuzzes - often cited as my favourite fuzz - because of its supreme versatility - two gain channels, 3-Band EQ, Clean Blend and Voltage Starve - what's not to like! While the BitQuest is very much its equal - and has I believe a somewhat similar but less EQ-granular Fuzz at its core (not aas high-gain either) - which you can then shape up and enhance with a 8 secondary effects including Bit Crusher, Ring Mod and Flanger - all to really superb effect. You can of course run it in clean Mode too - just for those effects in a more stand-alone fashion - while this pedal is a lot more fun with the Fuzz engaged - it's a quite brilliant sounding Modulated Fuzz. All those Patch options are superb - while it would be nice to have an updated version with the addition of tremolo / LFO - that works so well with fuzzes - and would raise this one up even a step further!


Drunk Beaver Drunk Beaver Fluff Fuzz + Octave + Boost (Enhanced Muff) - $150

close

Controls - Shift (Mid Scoop > Flat), Tone, Fuzz, Boost, Octave, Level, Fuzz Footswitch, Boost Footswitch.

 

The Drunk Beaver catalogue is immense - with so many gems to be found within it - but this is probably my favourite fuzz from that range - a superbly voiced Big Muff at its core with a potent Boost, Mids Shift Control and great sounding Upper Octave. This is really a proper next generation Big Muff - it sounds rich and full and just amazingly textured at all times. The cutesy artwork might do it a slight disservice - but this fuzz is immense!


El Músico Loco Wee Beaver Fuzz Small (Regulus VIII) - discontinued - $160 when new

close

Controls - Volume (Master), Contour.

 

Interestingly this very fuzz circuit is also at the heart of Chase Bliss's Limited Run Ayuhuasca Trem Fuzz - which mixes it up with a choppier version of the Gravitas Harmonic Tremolo. The Os Mutantes Regulus VIII was a very special high gain variant of Fuzz Face which can sound almost Muff-like at times. Another really potent pocket rocket in this format - built by an American native transposed to Spain - these weren't around for too long, and the maker has alas passed away in fairly recent years. It took me a long time to track down one of these - a few years I think it was! 


Fjord Fuzz Gjallarhorn V4 (Super Fuzz) - discontinued - $150 when new

close

Controls - Volume, Gain, Tone / Filter 1 (HPF), Octave Bias, Tone / Filter 2 (LPF), Momentary Tone Bypass Footswitch (Mid Boost), Bypass Footswitch.

 

Daniel Thornhill doesn't have a bad fuzz in him - all of his are grand! - while for me this Gjallarhorn V4 is incredibly special - and quite the different animal to the more recent Fenris - even though they are both based on the Super Fuzz circuit. Where the Ferris is more strident and searing, the Gjallarhorn is so well named as it's capable of the most magnificent wall-of-sound foghorn style of fuzz - deep, and resonant and just immense - a really booming style of fuzz that seems to carry that epic viking style foghorn sound through the ages. It's two Tone controls (HPF & LPF) take a while to get used to - but when you get them set just right - you get the most immense sound emanating from this pedal. Definitely something of a forgotten classic - which I've been trying to get Daniel to revive in another new edition. I'm guessing it may be a pedal of the month variant at some stage - but it's not on the schedule yet!


Free Fall Diver Huge (Muff Fuzz) - discontinued - ¥23,000 (c$160) when new

close

Controls - Volume, Sustain, Tone.

 

This was another one that I had to hunt down for several years. It's a take on the Big Muff circuit - but sounds really distinct - incredibly potent for its size - and just with the most wonderful range of singing sustaining tones - touching on the most beautiful liquid distortion at times, and pairs supremely with overdrives and distortions for the most beautiful of tones. I'm so glad that I managed to get hold of one of these - this fuzz is incredibly aptly named. I'm trying to track down more of Free Fall Diver's fuzzes - they did a superb Super Fuzz variant too - but these all seem to be as rare as hen's teeth nowadays - not seen any in the wild for the longest time now!


Kuro Custo Audio Akuma Fiery Fuzz - €169 (c$185)

close

Controls - Volume, Fuzz, Intensity (Input Gain), Active Hi EQ, Active Lo EQ.

 

This one is still somewhat under the radar while more generally available still. A 6 x Silicon Transistor Fuzz that is not a Super Fuzz - but somewhat adjacent to that. It deliver a really interesting mix of Regulus VIII style high gain Fuzz Face, Jordan BossTone, and Super Fuzz - with all manner of in-between voicings. A really expansive palette with some suitably clever controls - including Input and Output Gain and 2-Band Active EQ. A really potent versatile fuzz that deserves more attention.


Paul Trombetta Bone Machine GTX - discontinued - c$300 when new

close

Controls - Presence : Normal / Bright / Dark, Transistor : Ge / Si, T Input Cap : Stock / Thin, Range (Bias) : Hi / Lo, Volume, Gain, Bore (Thickness), Mood (Bias).

 

Yet another one which took me years to track down - fortunately pre-Brexit as I found this one in Italy - several years ago now - already at a high price - but not the obscene prices that these command nowadays. When I got mine - Paul was still making the occasional one - while his refusal to ship outside the USA is a problem for us Fuzz Fans in other parts of the world. I wanted one of these for several years - before one popped up for sale on Reverb.com - that was within my reach. It's a really unusual and versatile fuzz that does everything from subtle overdrive and fuzzy drive to almost Tone-Bender style voicings - courtesy of 8 really smart controls. The circuit is gooped up so it's not entirely clear to see what's going on - but it contains two Silicon Transistors and one Germanium I believe - where you can switch the second Q2 stage between Germanium and Silicon. Really sounds superb with lots of nuance and expressiveness a real chameleon of a fuzz. There are several Bone Machine variants - where the GTX is the DLX version - with the 8 controls and the most variety / granularity in its output.


ProAnalog Devices MKIV Vintage - discontinued - $299 when new

close

Controls - Level, Drive, Attack.

 

Despite his well documented character flaws, Scotty Smith is a really great circuit engineer and designer - and this is surely one of his finest ever creations. The MKIV moniker kind of indicates a Tone Bender adjacent nature - but even though it can overlap a touch with that smooth MKIII style liquid distortion sound - it's kind of it own thing really. It's a hybrid 3 transistor fuzz - utilising 2 x BC237B + 1 x CV7112 Ge Transistors and it has a really cool inherent smoothness and that smart interplay between 2 highly interactive Gain controls - Drive and Fuzz. It produces some really distinct fuzz and fuzzy-drive textures - most definitely a perennial favourite of mine!


Rainger FX DFST-1 Stealth Mini (Chop Fuzz) - discontinued - £229 (c$290) when new

close

Controls - Altitude (EQ), Overtone (Harmonic Overtones), Speed (Modulation Rate), Silence (Output), Awareness (Envelope Sensitivity), Pad : Guitar / Line-in, Mode : Step Modulation / Envelope.

 

Rainger FX's celebrated Dr Freakenstein Chop Fuzz has gone through as many as 11 major iterations over its lifetime, where I also own a black limited edition of the V3 / DrFF-3 full-size Chop Fuzz. This shrunk down limited edition was every bit as potent as those full size versions - of course with some concessions for its greatly reduced dimensions. I could have cited the Bleep Fuzz here - but that is probably in too wide a circulation to be considered a Secret Weapon. This Stealth enclosured device doubly fits the bill as a Secret Weapon - with is spy machine vibes. A fantastic sounding mini-fuzz for sure - which all 3 mini fuzzes in this selection undoubtedly are - and each distinctly different and unique. David was advised to release this as a limited edition - which is a shame really as I feel as many people as possibly should be able to get their hands on one of these - a really cool one-off for sure. And since the large format version has been discontinued for a while - we're probably due another version of that seminal fuzz very soon - I would still have liked to have seen this one remain in production - I guess more joy for those who snagged one!


Redbeard Effects Honey Badger Sub-Octave Fuzz - £219.99 ($280)

close

Controls - Volume, Divide : -2 > -1 Octaves / Mix, Octave (Level), Treble, Bass, Fuzz (Gain), Bypass Footswitch, Octave Footswitch.

 

I recently covered the very similar Way Huge Stone Burner - which conceptually is a somewhat stripped down version of the Honey Badger. Readers will know how much I value a second footswitch to switch in and out the Octave function - and it makes the Honey Badger extra special. Also the ability to blend the -1 and -2 Sub Octaves. I'm a huge fan of both Upper and Sub Octave Fuzzes - while there just aren't as many Sub Octave Fuzzes around - and certainly not of this caliber. The new Stone Burner sounds decent - but this is the original Mac Daddy - with even more up its sleeve. Of course another Thorpy production too - and he definitely has a way with fuzzes!


Shift Line Termofuzz (multi-fuzz) - discontinued - $165 when new

close

Controls - Level, Dirt (Self Oscillation . Random Octaves / 8 Bit / Glitch, Gain, 3-way Harmonics Switch - Less / More High Frequency Harmonics, Mode Dial : Low Gain, Gated, Octaves Down / Up, Arpeggiation, High Gain etc.

 

One of my all-time favourite fuzzes and probably still the most versatile one made - for the range of different fuzz tones you can eke out of it. Shift Line's Oleg recently posted a prototype teaser - where he's working on a new version of this long discontinued fuzz. I am so looking forward to getting my hands on one of those - and I hope it builds on the self same killer formula of the original - with its broad sweeping Mode dial. It can be a little fiddly on the dial-in every now and again - but it's supremely fun in discovering all those wonderful textures - both classic and quirky!


Toneczar Vault (Super Fuzz) - $395

close

Controls - Treble, Voice (Upper Bass > Low Treble), Bass, Fuzz Mode : XF eXtreme Fuzz + Octave Up / F1 Fuzz Only / F2 Fuzz + 2nd Harmonic Distortion. Deep (Bass Knob Range) : Up for Guitar / Down for Bass / Baritone, Gain, Content (Harmonic Content per Mode) : XF Octave Up Level / F1 Fuzz Level / F2 2nd Harmonic Distortion Level, Volume.

 

This was my first Toneczar pedal - which I serendipitously picked up second hand from an Australian Reverb.com seller. I had had my eye on this for a while - and at that moment it was perfectly priced for a quick buy - being also in pristine condition. This is a sort of High Gain Superfuzz which really has a wide palette of tones - via 3 core voicings and a smart 'Content' control which varies per voicing. Interestingly there are 3 killer Super Fuzz variants in this listing - the Crankled Bitoun, Gjallarhorn and this one - and they all sound quite distinctly different from each other - which is often the case with fuzz. You can have a similar core circuit delivering enitrely different results. The Crankled Bitoun is thick and textured, the Gjallarhon is resonant and booming, and this Vault is Searing and Sizzling - kind of leaning more into the high gain thing - but with tonnes of nuance too. It's a little pricey comparatively - but it really delivers! Actually - the Akuma Fuzz can also be included in this company - that one's sort of Super Fuzz adjacent - and again has its own distinctive tonality!


Final Thoughts

2023-GPX-Secret-Weapon-Fuzzes-700.jpg

It was not deliberate of me to select quite so many discontinued pedals - I guess part of the Secret Weapons allure is that something can be rare as well as being rarefied! While my wishes are always for as many players as possible to get their hands on these pedals.

 

Understandably some brands don't get the luck they need to sustain them longer term - and individual products and brands can fade in popularity and be discontinued. These 16 though remain perennial favourites of mine - I have them positioned fairly close to hand at all times so I can quickly deploy them on the board when I feel the need! All of these get regularly rotated in - while you won't necessarily be aware of it from the end of month Pedal Chain Status updates which of course focus on the new additions.

 

I feel all of these are well worth having - while probably the Bone Machine GTX would be prohibitively expensive these days - I've seen some going for near $1,000. I'm already campaigning for the Deus Ex Machina and Gjallarhorn to be revived - and it seems that there is a new version of Termofuzz fairly imminent too now.

 

And while half of these are discontinued the other half is still readily available - some of those are built in small batches fairly infrequently - so you will need to reach out and make the builder aware you want one of those.

 

I would love to hear from anyone who has any of these and what their experience of them is. Also let's hear which are your own secret weapon fuzzes that people may not be familiar with.

 

The theme here definitely has a focus on the less well known products and brands.
