Walrus Audio DFX-1 Percussion Processing Unit

The DFX-1 was developed in collaboration with Aaron Sterling to bring his studio workflow directly to the player. Aaron is one of the most in-demand studio drummers of the past 25 years with too many credits to list here. His focus on texture, feel, and creative control shaped every stage of development, resulting in a processor that bridges the gap between live performance and studio sound.

Drummers have long relied on a “fun mic” for creative color, often managed through engineers, plugins, or complex pedalboards. The DFX-1 delivers the control to drummers in a single, intuitive interface. Faster, cleaner, and designed for immediate, expressive control.
