An improved recreation of the rare vintage BOSS C1-E, the Warm Audio WA-C1 Chorus/Vibrato is a stereo modulation effect that will satisfy guitarists and keyboardists looking for authentic vintage modulation.
Just like the original, the C1 offers separate controls for vibrato and Chorus and a footswitch to toggle between the two effects (something quite unique among pedals of this kind). It also adds a Chorus Rate control that was missing from the BOSS unit.
That vintage chorus was also very sought after for its preamp, which is recreated in this pedal, including the high/low impedance switch that, in the high settings, allows not only compatibility with line-out instruments but also adds a pleasing, overdrive-like saturation to your guitar’s signal.
