KMA Machines Launches Special Edition WURHM Distortion

November 26, 2020 · 6 sources

German effects firm KMA Audio Machines announced the WURHM, a limited edition of its Wurm distortion pedal that pays homage to the Boss HM-2 with a black-and-orange enclosure echoing the original's color scheme¹. The pedal is a circuit based on the Boss HM-2, and KMA described it as an unabashed sonic love letter to that pedal, pushing further into destructive territory².

The WURHM was released as a limited batch of 200 units to celebrate the sale of more than 1,000 Wurms, after which production reverts to the stock white edition². MusicRadar reported the pedal as an HM-2 tribute getting an orange and black makeover³, and Guitar.com noted it was launched as a new limited edition of the Wurm, entitled the Wurhm⁴.

Compared with the original Boss HM-2, the Wurm and WURHM add two extra EQ controls, High Mids and Low Mids². Guitar Pedal X also reported that four dedicated interior trim-pots allow the player to shift the center frequency of each EQ control². Guitar World, however, described internal DIP switches for switching between the original HM-2 high control and KMA's own design; the two accounts differ on the internal adjustment on offer¹.

Key points from the announcement:

• Limited edition of 200 units, in a black-and-orange enclosure¹²
• Based on the Boss HM-2 circuit, with added High Mids and Low Mids EQ controls²
• Four interior trim-pots for shifting EQ center frequencies, as reported by Guitar Pedal X²
• Price of €219/£199, approximately $260 each¹
• Shipping worldwide from Audio Distribution Group⁵
• Every purchaser could claim a free limited-edition WURHM T-shirt⁶

Guitar Pedal X's Stefan Karlsson called the Wurm family "one of the very best and most controllable HM-2 types / alternatives on the market"². On tones, he wrote that the pedal lets players "hone and enhance your Swedish Death Metal tones to the ultimate degree - or else break with convention (like me)"². At the time of his checking, PMT was the only UK dealer listing stock².
