The Warm Audio WA-C1 is a faithful recreation of the most celebrated all-analog chorus & vibrato in guitar pedal history with additional no-compromise features for exploring legendary modulated tones. Like the original, the WA-C1 delivers the lauded all-analog preamp with lush chorus & vibrato tones. Additional features include separated depth and rate controls on the chorus side, and a selectable hi-z switch for more open tones with added clarity.
