The Hammertone® Boost delivers two distinct boost sounds in one unit, elevating your signal to new heights. The Type switch allows you to choose between a clean op-amp boost circuit for uncolored volume boost, or a JFET boost circuit that adds harmonically rich compression characteristic of vintage tape unit preamps. The center-dented Treble and Bass controls allow for easy, pure level boost without affecting EQ. Adjust the knobs to boost or cut frequencies to your liking. This versatile boost pedal offers a wide range of uses, from boosting your solos without altering tone, to driving an amp for natural distortion, to adding EQ character to your basic tone.
