The Warm Audio WA-C1 Mod is a compact, 100% analog stereo chorus and vibrato guitar pedal introduced as part of Warm Audio's space-saving Mod Series. It is a faithful, modernized recreation of the legendary 1976 Roland/Boss CE-1 Chorus Ensemble—the circuit made famous by artists like John Frusciante and Andy Summers.

Key Features & Modern Modifications


The WA-C1 Mod packs the exact premium Bucket Brigade Device (Xvive MN3007 BBD) circuit from Warm Audio's full-sized WA-C1 pedal, but introduces major upgrades for modern pedalboards:
  • Ultra-Compact Enclosure: Features a dramatically reduced footprint compared to vintage units and top-mounted jacks for easy pedalboard integration.
  • Selectable Preamp Bypass: Unlike the original units where the colored analog preamp was always active in the signal chain, the Mod version introduces a Vintage/Modern switch. "Vintage" retains the original preamp character, while "Modern" completely bypasses it for a transparent, clean signal path.
  • Expanded Chorus Controls: Features independent Depth and Rate controls for the chorus section, overcoming the limitations of the original vintage units which combined these into a single intensity knob.
  • Input Impedance (Hi-Z) Toggle: A rear-mounted switch lets you toggle between line-level input (ideal for keyboards/synths) and a Hi-Z mode designed to preserve high-end clarity when plugging in passive electric guitars. 
  • Clever Footswitch Implementation: A single heavy-duty footswitch handles operation. A single press turns the effect on or off, while pressing and holding seamlessly toggles between the Chorus and Vibrato modes. 
  • Stereo Outputs: Retains the classic single-input to wet/dry stereo output configuration for incredibly lush, sweeping modulation fields.
