The Soul Driven Boost and Overdrive pedal from Xotic Effects is a versatile and flexible tone-shaping tool that promises to preserve your guitar’s tone while adding just the right amount of “soul.” Players get gain and volume knobs, can push mid-range frequencies using the Mid Boost knob, and tighten the bottom end or rip into searing highs with the Tone knob. The pedal also features a Bass Boost dip-switch (accessible by removing the backplate) to make your boost even fatter.
