Vintage amp-like lower-gain muffy distortion

Skreddy Pedals™ 1971:

In 1971, Mike Matthews' Big Muff Pi sparked a revolution in fuzz.  Thick, creamy, and sustaining, but well-behaved and more amp-like rather than buzzy.

The Skreddy 1971 pedal combines the same elements of the early "triangle knob" BMP, like carbon comp resistors, ceramic capacitors, and 2N5133* transistors, into a design that has its gain pulled back just a bit.  This allows the distortion to retain a balance of tightness and openness and an even more amp-like feel as opposed to an overwhelming liquid fuzz character.

The effect is positively addictive!  And hard to classify exactly.  It's not an all-out fuzz so much as a distortion reminiscent of a cranked Laney or Mesa Boogie with plenty of sustain and a very chord-friendly gain structure.

* "...the mysterious FS36999 transistor found in vintage V1 and V2 Big Muffs, which was almost certainly 2N5133 transistors with a custom mark." --Kit Rae

Laney and Mesa Boogie are also trademarks of their respective companies.

Classic triangle-knob BMP style pedal that leans more toward the "overdrive" side than the "fuzz" side

Meaty, aggressive, tight, smooth, sustaining, cutting, warm--it packs all these characteristics together because it is so well balanced and ready for anything.  Retains the "stringiness" of your attack rather than swamping it out.  Your chords will have great string separation even though there's no lack of gain.

The Skreddy 1971 has that old-school charm because it's made from oldschool parts!


Regular 9v negative ground, 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.
