Warm Audio WA-C1 Warm Chorus Vibrato

Professor’s Notes

The WA-C1 brings the iconic ‘70s/‘80s analog chorus and vibrato into the modern era, adding expanded control, stereo I/O, and studio-quality build while preserving the unmistakable depth and shimmer of the original. If you’ve ever chased the lush chorus tones of The Police, Queen, or Rush, this pedal will deliver them.

Description

The Warm Audio WA-C1 Chorus Vibrato is a faithful, all-analog recreation of the most celebrated chorus/vibrato stompbox of the 1970s, built for today’s players. Known for its swirling stereo chorus, rich vibrato, and unique preamp coloration, the original set the standard for modulation pedals — and the WA-C1 captures every bit of that legendary sound with thoughtful improvements.

• The Definitive Original Chorus Stompbox: The WA-C1 reproduces the iconic all-analog chorus/vibrato pedal, complete with separate controls for Depth and Rate, plus selectable Hi-Z input for uncompromising tone. Mono or stereo output options expand its versatility.
• No Emulation, Pure Analog Preamp: Featuring a 100% analog preamp that adds bite, depth, and natural compression, the WA-C1 enriches tone even when bypassed. A dual DC-DC converter ensures robust power and authentic analog response from a 9V supply.
• Deep, Lush Chorus: Built around a carefully clocked Xvive MN3007 Bucket Brigade Device chip with premium components, the WA-C1 delivers the lush midrange depth and authentic movement expected from vintage analog chorus pedals.
• Rich, Three-Dimensional Vibrato: Switch to vibrato mode for rotary-like textures, funk wobble, or expressive lead modulation. A flashing LED monitors both effect status and modulation rate.
• Separate Depth & Rate Controls For Chorus: Unlike the vintage pedal’s single “intensity” control, the WA-C1 provides full independent adjustment of depth and rate for a wider palette of modulation tones.
• Selectable Impedance For Multiple Sources: Back-panel switch offers vintage 50k ohm or modern 1.1M Hi-Z input, optimizing response for passive guitars or other sources and preserving clarity even in bypass mode.
• Hand-Tested In Austin, TX: Every unit is carefully tested and inspected by Warm Audio’s team of musicians and technicians for consistent, studio-grade performance.

With stereo capability, lush chorus, and expressive vibrato, the WA-C1 delivers the modulation tones behind countless iconic tracks, updated with modern flexibility and Warm Audio’s premium build quality.
