The Jumbo Dirty Rooster Vintage Mini is a limited edition fuzz pedal from Stomp Under Foot, built as a modified version of the Colorsound Jumbo Tone Bender, the original early 1970s fuzz1. Years after creating the original Dirty Rooster from that circuit, the maker revisited the design, adding a mids control along with a few subtle circuit tweaks, and released it as the Vintage Mini1.
What it does
The pedal is a fuzz in the Jumbo Tone Bender tradition, and Stomp Under Foot points players toward a specific reference for its character: "Think Edwin Collins 'A Girl Like You' fuzz"1. That comparison is the maker's own description of the sound, not a claim that Collins used the pedal.
In the maker's words, the overall voice sits full, with a low end that stays bassy without turning muddy:
"Its overall sound is full, with a bassy but never muddy low end that sounds monstrous on chords. Lead tones are thick, c"
The Tone and Mids controls work interactively, which the maker says gives precise control over the midrange and the pedal's overall voice1. For a player, that means the two knobs are not independent filters: setting one changes how the other responds, so dialing in the midrange is a matter of balancing them together rather than adjusting a single mids slider in isolation.
How it differs from the Dirty Rooster
The original Stomp Under Foot Dirty Rooster was the first version of the modified Jumbo Tone Bender circuit1. The Vintage Mini differs in three ways:
- A mids control has been added, which the original lacked1
- A few subtle circuit tweaks were made to the design1
- It ships in the smaller 4"x5" vintage-style enclosure as a limited edition1
Power and build
The pedal runs on a 9V battery or a 2.1mm 9V adapter only1. The build uses NOS through-hole components, meaning new-old-stock parts with leads rather than surface-mount technology, and each unit is handmade in the U.S.A.1.
The adapter requirement is stated as 2.1mm 9V only, so check your power supply's plug size and voltage before wiring it into a board.
A note on the name
The Rooster name also appears outside Stomp Under Foot: JAM Pedals says the independent treble booster in its Tiny Amp Destroyer is based on JAM's own Rooster2. That is a separate product from a different maker, unrelated to the Dirty Rooster circuit.
