Warm Audio WA-C1-MOD Compact Stereo Chorus & Vibrato Pedal

Warm Audio WA-C1-MOD Compact Stereo Chorus & Vibrato Pedal

The Warm Audio WA-C1-MOD Compact Stereo Chorus & Vibrato Pedal delivers 100% analog modulation in a smaller pedalboard-friendly format with a bypassable analog preamp. Its MN3007 bucket-brigade device circuit produces chorus and vibrato effects, while independent Depth and Rate controls give players more control over modulation intensity and speed.

Designed for electric guitar, bass, keyboards, and other instrument-level sources, the WA-C1-MOD combines vintage-inspired response with modern signal-chain flexibility. A Vintage/Modern preamp switch lets players retain the analog preamp character or bypass it for cleaner gain staging. Selectable 50-kilohm and 1.1-megohm input impedance settings accommodate both vintage-style loading and higher-impedance passive instruments, while stereo outputs support spacious dual-amp and recording configurations.

The compact chassis uses top-mounted connections to conserve pedalboard space while retaining extensive analog circuitry. Inside are five integrated circuits, including three Texas Instruments audio op amps, 11 discrete transistors, three FETs, 19 diodes, two MOSFETs, and an MN3007 BBD chip recreation. A dual DC-DC voltage converter provides the internal operating voltage required by the vintage-inspired circuit, while a flashing LED gives visual feedback for effect status and modulation rate.

Key Features

• Analog Chorus and Vibrato: Uses a 100% analog signal path with an MN3007 bucket-brigade device chip recreation for classic modulation textures.
• Independent Effect Controls: Separate Depth and Rate adjustments for chorus and vibrato provide precise control from subtle movement to pronounced modulation.
• Bypassable Analog Preamp: Vintage and Modern settings let players choose preamp coloration or cleaner operation for complex pedal chains.
• Selectable Input Impedance: Switch between 50 kilohms and 1.1 megohms to accommodate different instruments and pickup types.
• Stereo Output: Dual outputs support wet/dry stereo operation for dual amplifiers, recording systems, and expanded modulation effects.
• High and Low Sensitivity: Selectable input sensitivity helps optimize the preamp response for different signal levels.
• Compact Pedalboard Design: Reduced dimensions and top-mounted jacks simplify installation on crowded pedalboards.
• Visual Modulation Feedback: A flashing LED indicates effect operation and modulation rate during performance.
