[0.1″ stripboard] La Pelusa Retro Fuzz

Ok… now – what the fuck is La Pelusa Retro Fuzz?

It’s Silicon “proprietary chip set” based version of well loved Tone Bender MKII fuzz unit my son!

Nothing to add, nothing to cut…

Layout contains full off-board wiring, and will fit into Hammond “B” type enclosure

Fuzz Face Family

Welcome to new section. Since t.org shows at least few projects based on good-ol Fuzz Face I decided to keep them all in one room. This is also good time to look at them again – correcting possible errors and update with new info.

Firstly – let’s look at Dunlop EJ-F1¬†Eric Johnson Fuzz Face. Attached project is based on 0,1″ pitch perfboard layout done at one point by Electric Warrior, with specific components added to match EJ-F1 spec, full off-board wiring as usual, no shielded wire, just like in real one.

So what we have here is basically standard Fuzz Face spec, originally Q2 resistor is paired with trimmer to set quite cold bias at 3v range. I decided to do it as an fixed bias for layout simplify and vintage look of sake of it. Just set the bias with potentiometer, pick  the closest value resistor from your stash and solder it in.

What we also see here is small value capacitors between transistors Collector and Base. In traced unit at Freestompboxes there is only Q2 limiting cap, SMD type, no marking visible, but it shouldn’t be big. Our B.man ¬†have one coming soon, so as soon as we get the correct info, let’s say it’s about 39pF. For Q1 there is no cap, but there is a place for one, perhaps in later issues, when/if/in case if Dunlop will use hotter transistors for Q1 this cap will be there, at this point with recommended transistor pair omit the fucker.

Lastly, we have small value 27R resistor in line with 15uF cap to prevent squealing and few shifts in component values making this unit unique. Give it a try!

And here is the same as abowe, but for .15″ pitch retro-style vero. Will fit into hammond 125B enclosure, nice and old-school


Another Dunlop Fuzz Face variant – Joe Bonamassa Signature Fuzz Face.

As my previous layout, this perfboard is based on Electric Warrior’s work with just few components added to match it to JBF-3 spec.

What’s the Fuzz is All About? Firstly, it has one more component to (AFAIK) prevent squealing at higher Fuzz settings.

Secondly, it’s PNP germanium circuit. Old stock Russian transistors ware used.

JBF-3 was short lived limited to 300 units only. It’s gone by now, so here’s your chance to build one.

I did another layout with external bipolar power supply, but I wasn’t sure connections, so I decide to let you see it as is – bare bone.

Another project is is made for 0,15″ pitch veroboard. It’s classic Dallas Arbiter silicon BC183L Fuzz Face. First Si transistor issue. Wide space vero I did is still small enough to be fit into Hammond B style enclosure. No mods, no fucking around, just a plain and simple silicon Fuzz Face we all love, and hate…


John Hollis RockFace

Here’s description from John Hollis website

What we see here is slightly twicked (to JBF3 spec) Fuzz Face circuit with Q2 collector autobias. How cool is that?

Few notes:
– Draw designed to accommodate C-E-B short leg transistors as I have quite large stash of old Russian Ge’s with that pinout. It shouldn’t be a problem since most ge’s are long legged, you can bend them as you wish…
– It’s not exact RockFace schematic take. 100n in John’s is 10n in my layout, 47uF cap from mid lug fuzz pot to V+ is standard 22uF in mine. I’ve added 10R anti-squeal resistor in line with that 22uF, as known in Dunlop JHF3 Fuzz Face. Pot values are also taken from new-ish Dunlop FF’s
– Triple checked – not verified

Small enough to be fit into B sized Hammond enclosure, I’ve draw it with 0,1″ pitch stripboard in mind

Get that there


More variants coming soon…


[Tagboard] Creepy Fingers Effects Si Fuzz Face


Here’s lovely tagboard layout for si fuzz face clone made by Brad from Creepy Fingers Effects for charity auction where 100% of the proceeds of auction will go to Naoto Matsumura and Tomioka’s animals. Very cool initiative and very nice fuzz face layout on single tagboard. Love it!

Small mods in circuit – added 10R resistor between Q2 emitter and fuzz pot plus small ceramic cap 39pF to lower noise and prevent oscilations on higher fuzz settings.

Transistors are TFK BC130c.

Corrected layout updated.

[Tagboard] Os Mutantes Fuzz / Deadpool


Here’s another cool project for ya – Os Mutantes Fuzz (a.k.a Regulus VIII) !

Circuit developed in 70’s by Cesar Dias for Os Mutantes guitarist.

Very unique sounding circuit powered by two silicon NPN transistors. Only one knob – Volume and Filter switch to cut bass response frequency. There’s also silicon diode clipping section for even more distortion and compression.

[Various] Maestro FZ-1 Fuzz Tone

Classic as hell. THE really first fuzz unit ever produced, popularized by guys who can’t get no satisfaction.

The only way to get buzzy tone before that was to slash the speakers with razor blades.

First layout is designed to go with 15″ pitch vero, vertical axial e-caps – if you use BC Electronics 63v they’re not longer than 1/2W CC resistors, so IMO it’s fine.

Two versions, both share the same component layout. First one is for kind-of TBMK1 mounting style, second one is made for MK2 bender style mounting brackets, the same crap, different flavor.

* Version I vero.pdf

* Version II vero.pdf

Full offboard shielded wiring sexy as me included.

Second layout is for perfboard/eyelet (your choice), old school charm and kind of back to the roots for me. Love to that kind of projects make me to set turretboard.org up! I need to make more of those layouts sometimes soon – get it here.pdf

[0.1″ pitch stripboard, tagboard] Elka – Dizzy Tone

Yo! Here’s vero layout for Elka Dizzy Tone!
Very rare vintage fuzz unit. It’s almost indentical to Baldwin Burns Buzzaround – just few components values are changed.

Get the project file [.pdf]

PAGE UPDATE 03/04/2012

Here’s tag board adaptation for Elka Dizzy Tone based on Buzzaround layout (just little smaller – should fit 125b enclosure).

In orginal unit as Q1 and Q2 where used SFT352 (schematic on fsb.org shows hfe around 50) and SFT308 or OC44 as Q3 (hfe around 70).
