Warm Audio WA-C1 Chorus Vibrato

The WA-C1 Chorus Vibrato is a faithful reproduction of the most celebrated all-analog chorus in the history of guitar pedals, enhanced with additional features to explore new possibilities for modulated sounds without compromise. The WA-C1 features a high-quality, all-analog preamplifier that is highly prized by guitarists who demand an ultra-responsive response. The chorus setting features separate controls for depth and speed, overcoming the limitations of vintage units while maintaining a sound true to the original. The vibrato section is authentically reproduced from the original pedals, and an added hi-z switch on the back of the pedal allows players to compensate for the higher impedance of guitars compared to keyboards, enhancing high frequency clarity if desired.

The ultimate original stompbox chorus

The WA-C1 faithfully recreates the most celebrated all-analog chorus and vibrato pedal, known for its pure tones and rich modulation. It combines a faithful circuit design with separate controls for depth and speed in chorus mode and an additional hi-z option for an uncompromising 100% analog chorus experience. The WA-C1 has a single input and both mono and stereo outputs.

No emulation, pure analog preamplifier

The WA-C1 features a 100% analog preamp, mirroring the original, with a level control that adds bite, depth, and a slight natural compression to guitar tones. The entire pedal circuit is supported internally by a voltage regulator that provides a robust power supply even when using an external 9 V power supply. The preamp tone adds color and character even in bypass mode.

Deep and classy chorus

The WA-C1 offers classy depth and detail on the midrange frequencies associated with analog chorus pedals such as the Bucket Brigade Device. Using a modern reproduction of Xvive's MN3007 BBD chip, along with high-quality components and boutique-level construction, the WA-C1 is carefully tuned to replicate the depth and speed of the original pedal, returning the detail expected from the most sought-after vintage pieces.

Rich, three-dimensional vibrato

When you want to get a truly vibrant sound, you can turn on the Warm Chorus Vibrato setting to add speed and dynamism to your tone. Experimenting with vibrato mode offers rotary-like modulation tones that are ideal for funk, fusion, blues, jazz and more. The WA-C1 includes a flashing LED on the front panel to monitor the effect, indicating which setting is active and the speed of the modulation.

Separate controls for chorus depth and speed

The WA-C1 has independent controls for depth and speed, unlike the intensity control of vintage models, which increased both depth and speed simultaneously. With the WA-C1, you can overcome these limitations by setting a greater depth and slower speed for even richer chorus tones.

Selectable impedance for multiple sources

The WA-C1 has a selectable impedance switch on the rear panel that allows you to choose between the 50k ohm vintage input impedance and the 1.1M ohm Hi-Z setting, which is ideal for passive stringed instruments to improve clarity. This switch also works in bypass mode, maintaining clarity of sound.
