Originally released in the heyday of guitar effects pedal inventions and distributed by Rose Morris, the Duo Fuzz combines two unique fuzz effect voicings that have been used by legendary guitarists from the likes of Genesis and The Who. Also known under the Univox name, the pedal has since fallen into the hands (and pedalboards!) of revered modern players too.

Rose Morris have collaborated with ThorpyFX to meticulously recreate the Duo Fuzz, in both its original big box glory and in a more pedalboard friendly compact enclosure. Fully handmade in the UK using a pair of NOS germanium diodes and a circuit board laid out just like the original units, we've paired all the mojo of a true vintage fuzz with premium build quality and modern reliability - ready for your stage or studio.

Now it’s your turn to stomp on a Duo Fuzz and make history!

Specifications

Balance - This controls the pedal’s output volume, either to match your level to the bypass signal, or push the front end of your amp harder for extra grit.

Expander - This allows you to add more gain and saturation to the fuzz sound, for a thicker, sustained tone.

Tone - The Tone switch is where the Duo Fuzz gets its name - use this to drastically change the sound of the pedal from bright and cutting to wooly and warm. This is a slider on the Heritage Edition and a footswitch on the standard pedal - a feature never before seen on a Duo FUZZ.

Power - The SHAFTESBURY DUO FUZZ takes standard 9 Volts power at 20mA, centre negative.
