JAM Waterfall Bass Chorus Pedal

JAM WaterFall Bass Chorus: Rich, Versatile Modulation for Bass

The WaterFall by JAM Pedals is a chorus/vibrato pedal that has been beloved by guitar, bass, and keyboard players for years. It's a mainstay on the boards of some of the greatest musicians like John Scofield, Nels Cline, Steve Lukather, Anthony Jackson, and John Medeski. The WaterFall has established itself as one of the best analog BBD chorus/vibrato pedals on the market, with an extremely versatile, rich, and 3D tone that has even converted the most rigid chorus-haters.

Unmatched Modulation Versatility

With two toggle-switches, the WaterFall offers users the ability to switch between chorus and vibrato modes, and to switch to a "wetter" effect resulting in a deeper, more contemporary sounding chorus or a more intense, deranged vibrato sound. This flexibility allows you to tailor the pedal's output to your specific musical needs, whether you're aiming for subtle modulation or dramatic, swirling effects. By maxing out the Depth and Speed controls, you can achieve Leslie-speaker type effects that add a unique, dynamic quality to your sound.

Intuitive Controls for Creative Freedom

The WaterFall Bass Chorus is equipped with user-friendly controls that make it easy to shape your sound. The Depth control adjusts the modulation's depth on top of the dry signal, while the Speed control sets the modulation speed. The "C / V" toggle-switch lets you choose between Chorus and Vibrato modes, and the "+ / -" toggle-switch allows you to select between discrete (-) or more pronounced (+) WaterFall modulation. Additionally, an internal trimmer lets you fine-tune the maximum modulation speed for even greater customization.
