The KMA Machines Wurm 2 is an update on the company's original Wurm, which pays its respects to the legendary heavy rock and metal pedal, the Boss Heavy Metal HM-2.
Check out its bigger brother, the Guardian Of The Wurm if you need a killer distortion with all the bells and whistles, including a noise gate.
The Wurm 2 takes the HM-2's legendary dual-band EQ and expands it to 4 bands, giving you maximum tweakability - ideal for getting your sound to sit perfectly in a mix or live-band situation.
KMA developed its own unique tone stack with an EQ Style switch to dial in your perfect heavy tones:
Each of the 4 frequency bands is centred around a certain frequency and offers +/- 8dB of boost:
Each band has an internal trim-pot to shift its semi-parametric centre frequency to fine-tune your tone even further:
As referred to above, you can now switch EQ modes externally (the original had this feature on an internal dipswitch). The enclosure of the Wurm 2 is also slightly smaller and features top-mounted jacks, making it even more pedalboard friendly.
A new internal dipswitch has been added to the Wurm 2 to activate an input filter which tames the high frequencies, smoothing it out and reducing feedback issues, especially when everything is maxed out in true HM-2 fashion.
