Skreddy PedalsTM

Ripping High Gain Oldschool Fuzz

Adjustable but not refined—an angry, raw, vintage-style 2-transistor fuzz with extra controls and tweaks to let you recreate oodles of classic fuzz sounds with minimum hassle

The Skreddy Pedals™ BC109 FUZZ  is made from silicon transistors for power and temperature stability, but it's darkened so you can get germanium-ish effects out of it too. 

The 2 transistors are piggybacked for better tone (smoother, lower noise than single transistors), giving this circuit 4 transistors total. 

The extra controls let you emulate different classic fuzz tones from the 60's and early 70's along with improvements for some of the issues those early fuzzes had (noise reduction, adjustable tone, and input impedance selector switch).  Can get frazzly or smooth, bright or dark.

This is a rude, biting fuzz that does not totally clean up with the volume knob; at very low guitar volume it's still slightly gritty sounding.  So it's not one of those "leave on all the time" fuzzes; it's more of a "stomp for mayhem" type of fuzz!  It's not just another Fuzz Face™ clone; it's more like a fuzz on steroids.

About the name BC109 FUZZ:
It refers to the part number of the transistors used and is certainly not a unique moniker.  In fact it's so generic it cannot be used as a trademark; that would be like claiming to own the terms "V8" or "327" as the name of an automobile model.  There are other products already out there using "BC109" as their name or part of their name (I know of at least 3 others, not to mention several other products named "BC108").  If you want to use the transistor part designation of your fuzz as its name too, nobody's gonna stop ya.  Or you could think up a unique name.  Either way is fine with me.


Do not share power with a daisy chain. Not because that would fry anything, but just because this circuit is very sensitive to ground-loop hum. In other words, it will create extra noise. It is typical, normal negative-ground, though; no special power requirements.

9v battery is not included.  If you use a battery, then remember to un-plug the input cable from the pedal’s input jack when not in use to prevent draining (or you can also just plug in a power-supply, which disconnects the battery).

You may supply external power through an AC adapter.  All Skreddy Pedals accept the industry-standard 9v DC plug (5.5mm barrel x 2.1mm center coax), negative tip.  Please use a quality, regulated, filtered power supply.

Classic Fuzz Tones

bullet From thin and buzzy to clear and cutting to rich and thick and syrupy
bullet Selectable input resistance lets it work great with humbuckers and get along with other effects too
bullet Stable at all temperatures but very sensitive to guitar volume knob changes
bullet Just leave the fuzz knob cranked or backed down a touch
bullet True bypass, LED, standard 9v power jack

VOLUME This VOLUME control gives you a LOT more output volume than most classic fuzzes, with unity gain around noon and plenty of boost beyond that.
BIAS The BIAS control lets you go from buzzy and low-fi to clear, louder, and more present. Sometimes referred to as a "MIDS" control since it does give you more (or less) of those too.
VOICE The VOICE control lets you go from bright and articulate to smooth and syrupy with that lovely upper-harmonic emphasis you hear in classic fuzz recordings. It's really nothing more than an extra guitar tone control. This fuzz sounds so sweet with the tone rolled down that you will love having this dedicated control right where it's at, freeing up the guitar knobs for all your other applications.
FUZZ The FUZZ knob is the control that sets the gain for this whole thing. Most fuzzes of this type sound best with the fuzz turned either all the way up or dialed back just a touch from max.
HB / SC The HB / SC switch adds a bit of resistance to the input in order to keep a humbucker pickup from swamping the circuit and causing it to have a gated attack. But it's also useful for helping this fuzz work together with other effects (like to keep a wah pedal from making that siren sound you get from driving it into a vintage-style fuzz, or that extreme, trebly fuzz you get if you use a buffered pedal in front, for example).



Skreddy BC109 FUZZ settings suggestions


To get lower-gain, overdrivey sounds (like some germanium-equipped fuzzes), just set the impedance selector to "HB".

Volume stays at unity gain, around noon, more or less, depending on the bias setting, which will interact with and require adjustments to the volume.

Fuzz stays either at max or backed down just a hair.  Your guitar volume will go from all-out fuzz at 10 to distortion at 9, heavy overdrive at 8, and all the way clean down at 3 or so.

These settings were worked out using a Stratocaster guitar.

Clock settings: 5:00 = max, 7:00 = min

*Sounds kinda like… BIAS VOICE HB/SC
 Eric Johnson (to emulate how he rolls off guitar tone for smoothness) 10:00 9:00 SC
 Jimi Hendrix germanium era 9:00 2:00 HB
 David Gilmour "Pompei" era 4:00 1:00 SC
 Jimmy Page/Yardbirds (TB Mk1.5 era) (use neck pickup, preferably) MIN 7:30 SC

Eric Johnson style...


Some Pagey/Telecaster stuff!


He loves this fuzz with the bias and the voice controls both rolled down! He recorded a ton of clips featuring this side of its personality...
