The KMA Machines Strokkur Treble Booster is a Germanium booster based on the classic Dallas Arbiter Rangemaster. The Rangemaster is highly regarded for its power and exploding harmonics when pushing a tube amp that is already on the edge of breakup. The Strokkur Treble Booster provides this same capability but with the potential to operate on the full frequency spectrum at the twist of a dial. It also includes a 2-band EQ to sculpt your tone further, making sure the Strokkur will match any amp and guitar setup. KMA Machines hand make guitar pedals in Berlin and use premium components and rugged aluminium chassis. The Strokkur Treble Booster is one of these quality units that provides a powerful and nuanced boost to your signal in a range of frequencies.
