DemonFX 66 Booster Pedal

If your high-gain rig feels loose or undefined, a good front-end boost fixes more than another EQ tweak. The DemonFX 66 Booster is a compact clean preamp/boost pedal designed to tighten low end, add attack, and push your amp or modeler harder while keeping the core tone intact.

Based on the Fortin Amplification 33 Booster (Fredrik Thordendal signature-inspired circuit, per listing), it is built for modern metal rhythm clarity, fast picking response, and cleaner gain staging. The added amp channel switch function also makes it easier to move between sounds on stage without tap dancing.
