High Gain Distortion and Noise Gate!

Fusing together KMA’s beloved WURM distortion with an intuitive, yet versatile noise gate, Guardian of the WURM is the perfect metal monster.

From chugging hard-rock, droning doom metal and grinding Swedish death metal, the beast abides!

But, through its highly tweakable control set, the pedal can be tamed to provide impeccable clarity to your riffs, making this the definitive dirt pedal for metal.

So here it is: crank it up and you'll feel the rage of the ancient WURM, while the Guardian will help you tame that beast when needed!

Guardian of the WURM serves up the perfect pairing for an evil and gritty tone that never gets out of control... unless you want it to!

An even more versatile WURM!

The WURM is KMA’s unabashed sonic love letter to the classic BOSS HM-2 MIJ.

Guardian of the WURM takes things even further by adding a bunch of really useful new features!

Features like a highly configurable 4-band Active EQ, 3 different clipping styles and a high-mids switch give you access to a much wider range of tones!

Plus, the new Clean Blend feature helps to preserve your natural core tone.

Simply twist the Blend control to mix in the original unprocessed signal, allowing the initial pick attack of your tone to breathe.

Tame the beast!

We all know drive circuits like this can be noisy malice monsters!

To get a grip on the potential noise floor, KMA designed a sophisticated, yet easy to use Noise Gate.

This is based on a high-performance Blackmer VCA and provides lightning fast and precise performance.

Simply set the Threshold to taste via the GATE control and enjoy the silence.

Fast palm-mutes? No problem. Decaying notes? Dead simple to accomplish!
