KMA Machines Wurm · Guitar Effect

The Berlin effect forge KMA Machines has revived the good, old HM-2. This relic from the 80s, without which the "Sweden metal" bands with their crisp chain saw sound would not have existed. As usual with KMA the resourceful experimenters have souped up the original circuit as far as they can go. The sound control has been expanded with 2 additional bands, but this isn't all: the internal frequency of each sound can be changed by means of an internal trim potentiometer for individual fine tuning. With an internal DIP switch you can set 3 EQ Modes: HM-2, the classic sound worm, the crisp sound and a combination of both settings.
