KMA Machines WURHM

The black and white KMA Machines WURM (without “H”) distortion was released in 2018 as a modern take on the BOSS HM2 MIJ pedal, a favorite of Swedish chainsaw metal players from bands like Dismember and Entombed, integrating the original’s active EQ with two more bands for a total of four EQ controls (Lows, High Mids, Low Mids and Lows). Each band has an internal trim-pot to change the center frequency and fine-tune your tone:

Activating Switch 1 alone selects the WURHM high-mids mode.
To get the classic HM2 ‘chainsaw’ high-mids character however, put switch 1 in the off position and switch 2 to on, crank the LOWS and the HIGH MIDS and rip that Swedish forest to shreds.
Activating both switch 1 and 2 together though gives you three bands, which are controllable via the HIGH MIDS control.

The German company recently unveiled a black and orange version of the pedal referencing the original’s color scheme, called WURHM.

Calling a pedal legendary or a cult classic is often stretching the truth, but when it comes to the Boss HM-2 MIJ it’s just spot on. From its absolutely brutal and grinding distortion tones it birthed an entire metal genre, while its thick walls of gain and sustain also saw it solidify its place within shoegaze and prog rock. We’ve never tried to hide the fact that our WURHM Distortion is our unabashed sonic love letter to this filthy box of doom and gloom, but taking it much further and pushing the envelope of how destructive it can be.

So, we only saw it fitting to adorn our mega metal monster in the iconic black and orange colors, not only to really profess our love and admiration but to also celebrate the milestone of 1000 WURM units that have now been made. Only 200 WURHM Distortion pedals will be created and available in this finish, plus in addition, every purchaser of a WURHM can claim a free* limited-edition super cool WURHM T-Shirt. So, if you’re looking for a modern and versatile take on this seminal shred machine that actually looks as evil as it sounds, then now is your chance!

KMA Audio Machines brings you the legendary distortion sound from the out of production Boss HM2 MIJ pedal. Its sound was a key element of the Swedish chainsaw metal, invented by Bands like Dismember and Entombed.

Taking the essential ingredients of this classic, while in the process developing a way more flexible metal-distortion pedal, we kept the classic active EQ section and added two more bands, giving a much wider range of tones to tailor your evil and gritty distortion sound. Each band has an internal trim-pot to change the centre frequency and fine-tune your tone. To switch between the original HM2 high control and our own designed WURM mid-band, we added internal DIP switches for even more tonal variations. Activating Switch 1 alone selects the WURHM high-mids mode. To get the classic HM2 ‘chainsaw’ high-mids character however, put switch 1 in the off position and switch 2 to on, crank the LOWS and the HIGH MIDS and rip that Swedish forest to shreds. Activating both switch 1 and 2 together though gives you three bands, which are controllable via the HIGH MIDS control. TERROR dials in the malice and the evil distortion sound you are searching for! Crank it up and you will feel the rage of the ancient WURHM.
