The Wilson Effects Angry Goat is a dual overdrive pedal that puts two much-copied circuits in one compact box: a Klon-style overdrive on one side and a Dumble-style overdrive on the other. Wilson Effects calls it "a faithful recreation of a K-circuit combined with a Dumble style circuit," and the two halves can be run separately or stacked together1.
The idea is straightforward. Instead of carrying two pedals, you get a D-style drive for smooth, touch-sensitive overdrive at subtle to moderate gain, and a K-style side that works as a punchy, dynamic boost on its own or as a push into heavier saturation. Delicious Audio, covering the pedal in 2021, described it as combining "two of the most sought after overdrive tones ever into one compact box"2.
The D-style side
The D-style half is modeled after the Dumble-style drive, the circuit family voiced after Howard Dumble's amplifiers. Wilson Effects says this side "offers smooth, touch-sensitive overdrive, perfect for subtle to moderate gain tones"1. On the maker's product page it is described as a moderate overdrive, ideal for subtle to moderate drive sounds3.
For a player, that places this side in the territory of amp-like breakup rather than high-gain distortion. Wilson Effects adds that the pedal "works exceptionally well with already overdriven amplifiers, adding warmth, sustain, and dynamic breakup"1, so it is designed as much for pushing a cooking amp as for creating drive on its own.
The K-style side
The other half is based on what Wilson Effects calls "the infamous Klon-style circuit," a reference to the Klon Centaur Professional Overdrive, the 1990s pedal that Klon-style circuits reproduce. Delicious Audio notes the two sides are voiced "respectively after the Dumble amplifier and the [Klon Centaur Professional Overdrive]"2.
Wilson Effects says this side "delivers a punchy, dynamic boost that can be used on its own or to push your amp or the D-side into full-blown saturation"1. In practice that makes it the more aggressive half: the maker describes kicking in the K side "for a boost in drive and heavier playing"3.
Stacking the two sides
The two sides do not have to be chosen between. Wilson Effects says you can "use each side independently or combine them to create an unstoppable wall of overdrive and sustain"1, and the product page adds that either side can be used "to push your already overdriven amp"3. Running the K side into the D side, or the whole pedal into an amp already on the edge of breakup, is the stacking use the maker has in mind.
Bypass and buffering
The two sides handle bypass differently, and this is the detail worth knowing before the pedal goes on a board31:
| Side | Bypass | What it means |
|---|---|---|
| D-style | True bypass | Pure signal integrity when off1 |
| K-style | Buffered bypass | Stays in the signal path and acts as a buffer when bypassed1 |
Wilson Effects says the K side "retains the buffer that makes this pedal a great addition to your board as it acts as a great signal buffer"3. For players who want a buffer at a specific point in the chain, that is a feature rather than a compromise; for players who prefer a fully true-bypass board, it is a fact to weigh. Delicious Audio confirmed the same arrangement, with the D side true bypass and the K side buffered in bypass2.
Power, price, and buying details
The Angry Goat runs on a 9VDC 2.1mm center-negative power supply, the industry-standard arrangement used by most pedalboard power supplies1. It is listed at $200.00 USD on the Wilson Effects site (October 2026)1.

Questions
Is the Angry Goat true bypass or buffered?
It depends on the side. The D-style side is true bypass, which Wilson Effects describes as preserving pure signal integrity. The K-style side uses buffered bypass, so even with that side switched off it stays in the signal path and works as a buffer for the rest of your pedalboard.
Is the Wilson Angry Goat a Klon clone?
Half of it. Wilson Effects describes the K-style side as based on the infamous Klon-style circuit, delivering a punchy, dynamic boost. The other half is a Dumble-style overdrive circuit. So it is one Klon-style circuit paired with one Dumble-style circuit in a single enclosure, not a straight Klon reproduction.
Can you use both sides of the Angry Goat at once?
Yes. Wilson Effects says you can use each side independently or combine them, and that the K side can be used on its own or to push your amp or the D side into full saturation. The maker also positions it as a tool for pushing an already overdriven amp.
Where is the Wilson Effects Angry Goat made?
It is handmade in Guilford, Indiana, by Wilson Effects, which says it uses only high-quality components. The maker also covers the pedal with a one-year warranty on parts and labor.
