Walrus - Badwater - Bass Pre-Amp / D.I. Pedal

The Badwater is a bass tone magnification device sonically highlighting what makes bass so crucial to music. The all-in-one bass pre-amp and DI features optical compression, overdrive, and a four-band EQ section. Enhance your bass rig’s capabilities and dial in everything from warm cleans, gritty chords, punchy drive, or bright and crisp slap sounds.

The Badwater gets its name from the Badwater Basin in Death Valley, California, the lowest point in the U.S. below sea level. Like the basin it’s named after, the Badwater holds the foundation for the lowest frequencies and saltiest licks in song creation.
