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.
