The Wampler Pedals Low Blow is an overdrive/distortion pedal that's made by and for bass players! The Low Blow Bass Overdrive from Wampler Pedals is a killer bass overdrive/distortion pedal that's made with the bass player in mind. Specially voiced for the low frequencies of bass guitars, the Low Blow features two unique clipping modes -- Smooth and Jagged -- that can you anywhere from a nice subtle drive tone to over-the-top bass distortion. The Smooth mode delivers more of an overdrive sound while the Jagged mode gives you more distortion. For full sonic control, the Low Blow comes equipped with an active 3-band EQ featuring Bass, Mids, and Treble controls. The switchable Notch Filter allows you to tighten/clean up that unwanted cabinet "woof" without having to turn down. Other features include a Blend control knob, a Level control knob, a Gain control knob, Wampler's standard top-mounted jacks and Wampler's soft click electrical relay true bypass switch. Handbuilt in the U.S.A. Powered by either a 9V battery or an optional 9V adapter.
