The Warm Audio WA-RB delivers bold, unconventional modulation and ring-modulation effects inspired by one of the most iconic experimental processors of the 1990s, offering everything from subtle lo-fi textures to intense, piercing infinity-style ring modulation. Designed for musicians and sound designers seeking unique tonal exploration, the WA-RB recreates the distinctive analog character of the original unit, making it ideal for crafting otherworldly sounds, layered harmonics, and unconventional sonic textures. Whether used for ambient effects, aggressive modulation, or abstract sound manipulation, the WA-RB opens the door to limitless experimental creativity.

Built for versatility beyond traditional guitar applications, the WA-RB accepts guitar, bass, synthesizers, and line-level signals, allowing players and producers to manipulate virtually any source with its expansive modulation capabilities. Dedicated controls for LFO Amount, LFO Rate, LFO Waveform, Modulator Frequency, and Modulator Mix provide deep sound-sculpting flexibility, giving users precise control over modulation depth, harmonic complexity, and movement. Its extensive input/output connectivity and intuitive layout make it easy to shape everything from subtle movement to wildly transformed textures with complete creative freedom.

Powered by a 100% all-analog signal path, the WA-RB uses premium TL072ADR op-amps and MMBT3904 transistors to deliver authentic analog warmth, responsiveness, and rich harmonic detail that digital recreations cannot replicate. Every unit is meticulously hand-tested in Austin, Texas to ensure premium build quality and performance consistency. Combining boutique-inspired circuitry, expansive control options, and rich analog experimentation, the Warm Audio WA-RB is the ultimate creative tool for players and producers looking to push sonic boundaries and discover entirely new sounds.
