Agent Omega, 12.05.2020
Wer auf den klassischen Buzzsaw Sound schwedischer Death Metal Bands der 90er Jahre àla Entombed steht, der bekommt mit dem Wurm ein Pedal, das einem Boss HM 2 dieser Zeit wohl so nahe kommt wie kaum ein anderer Klon dieses Sounds. Wer es obendrein noch gerne variabler hat, der ist hier erst recht gut bedient: Mit diesem kleinen grimmigen Kasten ist auch eine ganze Bandbreite amtlicher Fuzzsounds im Bereich Stoner und Doom im Rahmen des Möglichen. Im Inneren kann man mittels DP Switches zwischen Wurm- und HM2-Modus hin und her schalten, zudem sind dort die Frequenzbereiche des EQs zusätzlich anpassbar, was noch mehr Flexibilität in punkto Sound bringt. Verarbeitung und Design sind tip top. Einziges klitzekleines Manko: Die Energieversorgungsmöglichkeit mit einer 9V Blockbatterie wäre wünschenswert gewesen, daher ein kleiner Stern Abzug bei den Features. So ist man, sofern nicht bereits vorhanden, auf den Zukauf eines Netzteils angewiesen (am besten hochwertig, um Rauschen, Brummen und Fiepen zu vermeiden).
Für meine Belange ein 1A Kauf - ich habe den Wurm derzeit in der Band im Proberaum vor einer angezerrten Marshall Transistor Gurke in Betrieb und dieses kleine Monster wertet den Amp um ein Vielfaches auf. Bereue den Kauf nicht im Geringsten.

A Hammer!
Alexrann, 11.12.2017
With the massive amount of HM-2 clones on the market and opinions divided between good informed opinions and "fan-boy-blind loyalty-dirt flinging-twoodle" it can be/was a nightmare deciding which pedal to buy. There are a few good demos of this pedal online but once you put it through an amp in person you have no idea how evil this pedal is. I plug it into the clean channel of my Engl Fireball MK1 and the snarl and bite this pedal produces is ridiculous. It really pushes a tube amp to the dark side.

There's 3 eq modes to this pedal 1 being the classic hm-2 setting, the 2nd being the "wurm-eq" and the 3rd being both eqs together. I found that the 3rd mode gives the best of both worlds. The old-school nastiness of the hm-2 with a modern punch and feel.

I use it for metal but with the different eq modes this pedal is a lot more versatile then a standard hm-2 and I'd imagine it can be used for many different genres of music.

I highly recommend this pedal for any fans of bands like Nails or Dismember seeing how this pedal easily handles modern and old-school tones.

"HM-2-Nachbau"? - Eine Beleidigung!
Stephan1543, 27.05.2020
Auf der Suche nach einer Grindcore-tauglichen Zerre hab ich das offizielle YouTube-Demovideo dieses Pedals entdeckt und sofort bei Thomann bestellt.

Ja, die HM-2-Emulation klingt für mich sogar besser/durchsetzungsfähiger/direkter als das Original, aber ist nur eine nette Nebensache!
Dieses Pedal hat das, was ich von einem Distortion-Pedal erwarte, und zwar Eigencharakter!
Sehr interessant finde ich die vielfältigen Möglichkeiten, die sich mit den Reglern erzielen lassen und dass dieses Pedal sich klanglich zwischen Stoner-/Doom-/Fuzz-Klängen und fiesem Schweden-Deathmetal bewegt.
Allerdings bringt das auch Tücken, da Frequenzanhebungen oder -absenkungen auch die Zerre verändern - das Pedal wirkt dadurch sehr eigenwillig - direkt lebendig ;)

Was dieses Pedal den meisten Distortion-Pedalen, die ich getestet hab, voraus hat: Es setzt sich im Bandkontext hervoragend durch und liefert dennoch ein dreckiges Brett ab.

Etwas enttäuscht haben mich lediglich die Switches und Regler im inneren:
Switches:
Wenn man vom HM-2 auf Wurm-EQ umschaltet, passiert nicht mehr diese Mittenübersteuerung(?) wenn man die Hochmitten auf Anschlag dreht. Den Mehrwert sehe ich nicht wirklich - man kann diese Sounds doch eigentlich auch im HM-2-Modus erzielen.
Der Sinn des kombinierten HM-2/Wurm-EQs erschließt sich mir gar nicht.
Regler: Ja, sie machen was, aber das geht im Gesamtsound irgendwie unter und ich glaube, ich werde es nicht brauchen.

Fazit: Nachdem sogar mein Drummer bei diesem Pedal dezente Begeisterung gezeigt hat, wird es wohl die 30-Thomann-Tage bei mir überstehen ;) Ein innovatives, durchdachtes Pedal, was richtig Spaß macht und sein Geld wert ist!

CHAINSAW!
Ancient Iron, 14.11.2018
This pedal captures the tones of original BOSS HM-2 MIJ extreamly well. But there are much more in this pedal. With the 4-band EQ yoy can get allmost every tone you want and the sound allways stays focused. I use this pedal on both, guitar and bass. The internal trim pots makes it easy to adjust the EQ?s center frequencies to suit your liking or to finely tune it to work better for example if used with bass.

A classic Ibanez Tubescreamer or Colorsound Tonebender can fetch many times its original price from guitarists in search of the ultimate killer tone and sustain.
