Are you seeking to add a boutique-style new distortion pedal to your setup, with an awesome range of sounds at your disposal? How about if you get a free T-shirt with it? Then you've come to the right place!

An Orange Terror From Below!

With the KMA Machines Limited Edition Wurhm you get a boutique-style distortion pedal that basks in the kind of brutal and grinding distortion tones which helped to birth an entire genre of metal.

Inspired By A Classic

Influenced largely by the now-out-of-production HM-2 MIJ stompbox, KMA Audio Machines have fitted an impressive array of fine-tuning capabilities to the circuitry, allowing the WURM to produce a huge variety of distortion sounds.

This additions give the Wurhm the capability to be as dark and evil sounding as you could want it to be.

Active Four Band EQ

In addition to the Volume (output level) and Terror (level of evil) pots on the WURM, you also get an awesome 4-band EQ.

The controls on this section allow you to adjust Lows, Low Mids, High Mids and Highs, helping you sculpt that perfect tone for your guitar.

Further Fine Tuning

Under the chassis there's more tuning possibilities, in the shape of trim pots that further allow you to shape your sound.

These trim pots allow you to shift the centre frequency of each EQ's bandpass, and even activate/deactivate the classic HM2 EQ for the high mids to give you that famed Swedish Chainsaw sound made famous by bands such as Dismember and Entombed.

All in all the WURM is easilly one of the most versatile metal distortion pedals on the market.

Handmade Boutique Construction

Each and every KMA Audio Machines pedal is designed, assembled, silkscreened, tested, and numbered, by hand in a small Berlin workshop.

Despite the premium-grade components and boutique construction though, pedals like the WURM remain an affordable option for most working musicians and tone enthusiasts alike.

Limited Availability

Created to celebrate the creation of the 1000th Wuhrm pedal, KMA Machines have designed this limited run of 200 with stunning Black and Orange artwork in place of the more traditional White and Black.
