The Warm Audio WA-C1 Mod Series is a compact, all-analog stereo chorus and vibrato pedal based on the architecture of the classic Roland/Boss CE-1. It retains separate chorus and vibrato controls while reducing the enclosure size for easier pedalboard integration.

The chorus and vibrato sections each provide dedicated Depth and Rate controls, allowing the modulation of each mode to be adjusted independently. A Chorus/Vibrato switch selects between the two effects, while the Effect On/Off control handles bypass operation.

Warm Audio also equips the WA-C1 Mod with selectable High/Low input sensitivity and an adjustable preamp level. A Vintage/Modern preamp switch changes the preamp configuration, and the preamp circuit itself can be bypassed when a more direct signal path is preferred.

The Mod Series redesign adds a substantially smaller enclosure and top-mounted connections while preserving the WA-C1’s 100% analog signal path. Stereo operation further expands the pedal’s usefulness for dual-amp, recording and stereo pedalboard setups.
