A true double feature, the Hammertone� Boost pushes your signal to new levels with two distinct flavors of boost in one enclosure. Use the Type switch to select between a pristine, clean opamp boost circuit designed for colorless volume boosting and a JFET based boost that fattens your signal with a taste of harmonically rich compression characteristic of preamps in vintage tape units. Easily attain a completely flat boost thanks to the center detents on the Treble and Bass controls or adjust each knob to your liking - boosting and cutting frequencies as you see fit. This all-in-one boost pedal is capable of solo boosting with no added coloration, pushing your amp into breakup, sweetening your core tone, and so much more.
