Each band has an internal trimpot to change
the center frequency and ne-tune your
sound. To switch between the original
HM2 high control and the KMA
Audio Machines designed EQ
band, we added an internal DIP
SWITCH. Switch 1 activates the
WURM EQ High Mids Mode
while switch 2 is in off
position. To get the HM2
chainsaw high mids put switch
1 in off-position and switch 2
in on-position, crank the
LOWS and the HIGH MIDS to
hear the chainsaw. Activating
switch 1 and 2 gives you then
three bands, which are
controllable via the HIGH
MIDS controller. TERROR
dials in the malice and evil
distortion sound you are
searching for! Crank it and you will
feel the rageous ancient WURM.

Internal Controls 1
Each EQ has a trim pot to shift the center
frequency of the bandpass. Shifting the
center frequency changes the bandwidth of
the bandpass. That means, when you raise
the center frequency the bandwidth will
increase and vice versa.
The frequency range goes from:
WURM –DisTortion
Its dark legend is being told for thousands of
years—an old creature, full of grief and malice
will bring destruction and terror over the
tracts of land. Feel the fear and the
destructive energy of that ancient
monster with the WURM.
KMA Audio Machines give you
the legendary distortion sound of
the out of production HM2 MIJ
model. Its sound was a key
element of the Swedish
chainsaw metal invented by
bands like Dismember and
Entombed.
We took the ingredients and
developed a way more exible
distortion pedal. We kept the
classic active EQ section and
added two more bands to give
you a wider range of tones to tailor
your evil and gritty distortion sound.
