The WA-C1 Chorus Vibrato is a faithful recreation of the most celebrated all-analog chorus in guitar pedal history with additional no-compromise features for exploring legendary modulated tones. WA-C1 starts with a premium, all-analog preamp known for being a favorite of guitar players who demand ultra-responsiveness. The lush chorus setting features separated depth and rate controls to expand beyond the limitations of vintage units while delivering true-to-original tone. The vibrato section is preserved as authentic to the original pedals, and an added hi-z switch on the back of the pedal allows players to compensate for higher impedance of guitars vs. keyboards to add clarity to the high end on guitars if desired.

Key Features

  • No Emulation, Pure Analog Preamp – The WA-C1 has a 100% analog preamp, matched to the renowned original, with level control that adds bite, depth, and even some natural compression to guitar tones. The entire pedal circuit is supported internally with a charge-pump voltage regulator to deliver robust power even when using an external 9V power supply. The preamp tone adds color and tone even in bypass mode.
  • Selectable Impedance For Multiple Sources – WA-C1 has selectable impedance on the back panel to select between the vintage input impedance of 50k ohm and a 1.1M Hi-Z setting better suited for passive string instruments to bring out clarity. This switch works in bypass mode to maintain clarity in bypass mode.
  • Hand-Tested In Austin, TX – Like all Warm Audio gear, the WA-C1 is meticulously hand-tested and inspected by trained technicians with a passion for making music in Austin, TX USA.

The Definitive Original Chorus Stompbox

The WA-C1 faithfully recreates the most celebrated all-analog chorus and vibrato pedal known for pure analog tones and rich modulation. The WA-C1 combines a faithful circuit design with separate controls for depth and rate on the chorus side and added hi-z selection for a no-compromise 100% analog chorus experience. WA-C1 has a single input with both mono and stereo output operation.

Deep, Lush Chorus

The WA-C1 delivers lush midrange depth and detail associated with proper Bucket Brigade Device analog chorus pedals. Leveraging a modern MN3007 BBD chip recreation by Xvive with other premium components and boutique build quality, WA-C1 is carefully clocked to match the depth and rate of the original pedal to reproduce the detail expected from the most sought after vintage pieces.

Rich, Three-Dimensional Vibrato

When it’s really time to wobble, engage the vibrato setting on Warm Chorus Vibrato for added speed and bounce to your tone. Experimenting with the vibrato side yields rotary-like modulation tones perfect for funk, fusion, blues, jazz and more. WA-C1 adds a flashing LED for effect monitoring on the face showing which setting is engaged along with the rate of the modulation.

Separate Depth & Rate Controls For Chorus

WA-C1 has separate depth and rate controls vs. the vintage “intensity” control. On vintage units, “intensity” increased both depth and rate simultaneously, with the WA-C1, you can go beyond the limitations of vintage pedals by dialing in more depth and slower rates for even richer chorus tones.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.

Rotary

Rotary pedals recreate the swirling, moving sound of a rotating speaker cabinet, adding rich modulation and a sense of motion to guitar tones. They typically simulate the changing pitch and volume caused by spinning speakers, producing anything from subtle shimmer to deep, pulsating swirl. Rotary effects are often used for clean and lightly driven sounds to add depth, movement, and a classic, organ-inspired character.

Vibrato

Vibrato refers to a guitar pedal effect that modulates pitch slightly up and down, creating movement and a sense of wobble in the sound. Unlike tremolo, which changes volume, vibrato affects pitch only, producing anything from subtle shimmer to pronounced, warbling textures. It is often used to add character, depth, and vintage-style modulation to guitar tones.
