Iceland, a place full of myths, miracles and fairytales. Mighty forces are dozing underneath the barren valley of Haukadalur. A Geysir, so graceful, letting you stand in awe to the power of nature. Its name is Strokkur, the namesake of KMA Audio Machines' Germanium Treble- to Full-Range Booster.
Strokkur is KMA Audio Machines' inspired take on the iconic Dallas Arbiter Rangemaster. Well known for its power and exploding harmonics when pushing a tube amp on the edge of breakup, this pedal has helped shape and define legendary guitar tones throughout the ages. Now with Strokkur's updated and refined feature-set, these tones are ready to rock and inspire a new generation of players.
Strokkur is equipped with hand-selected NOS AC125 Tungsram transistors in order to stay true to the power and tone of the original, all while standing out from other germanium treble boosters on the market with its additional RANGE control and its two-band EQ-Section. This allows players to perfectly sculpt their own boosted tone, so it'll suit any amp, any instrument and any style! With its RANGE control, you can dial in anything between the classic treble booster sound to a full range boost, giving you a meaty sound with tight low-mids. The BOOST control, although not in need of much explanation, is very powerful. Set it low and simply use Strokkur as a subtle tone shaper, or begin cranking it and hear your tone shoot and soar into Rock'N Roll heaven with its mighty 17dB of boost on tap.
We added a passive TREBLE and BASS control to fine-tune your sound. TREBLE tames the high frequencies and the transients (>2.4kHz) when the boost is fully cranked, which helps you to quickly find the sonic sweet spot in combination with your amp. BASS helps to prevent overloading the amp by cutting lower frequencies (<240Hz), but leaves the low-mids untouched. Works especially well with humbucker guitars. Unlike most germanium boosters on the market, Strokkur is fitted with an internal DC converter and hence works with every regular 9V DC supply without fuss.
So, plug in your guitar and feel the force of nature!
Powered by an optional standard 9V DC (max.) PSU (negative center, 2.1mm, approx. 12mA current draw)
Every pedal is designed, assembled, silkscreened, tested and numbered by hand in our small workshop. We use doublesided PCBs which are designed, tested and assembled by ourselfs, to guarantee a high quality standard and keep the price of our pedals reasonable. The use of an indestructible powdercoated die-cast enclosure ensures a maximum durability.
