Warm Audio WA-C1 Chorus Vibrato Mod

Fan-Favorite Chorus, Pedalabord-Friendly Format

WA-C1 Mod packs all of the vintage tones, functionality, and vibe of the famous original chorus/vibrato pedal into a pedalboard-friendly design, while adding even more tonal flexibility. Like the larger-format Warm Audio C1, the WA-C1 Mod has a dedicated vibrato section and 100% analog preamp, now with a Vintage/Modern switch to choose between the character and response of the original preamp or bypass it for cleaner, more modern chorus tones. The carefully designed circuit brings the vintage depth of the modulation when turned all the way up, with variable depth to dial back for subtle tones. With a reduced footprint and top-mounted jacks, WA-C1 Mod delivers rich depth and wobbly rate in waves while taking up less space on your board.

FEATURES

• The Definitive Analog Chorus - With Modern Mods
  The WA-C1 Mod faithfully recreates the most celebrated all-analog chorus and vibrato circuit known for pure analog tones and rich modulation. The modified WA-C1 combines our celebrated circuit from the larger pedal, and adds the ability to bypass the preamp to work with setups that require meticulous gain-staging, all in a more compact, pedalboard-friendly enclosure. The 100% analog chorus pedal preserves the single input stage with wet/dry stereo output, and leverages top-mounted jacks with an ergonomic design to easily slot into any board. 

• No Emulation, Pure Analog Preamp
  The WA-C1 Mod has a 100% analog preamp, matched to the renowned original, with level control that adds bite, depth, and even some natural compression to guitar tones. The WA-C1 Mod pedal preserves this preamp and also allows for quick bypassing by engaging “modern” mode over “vintage” to manage complex gain-staging in signal chains. The entire pedal circuit is supported internally with a dual DC-DC voltage converter to deliver robust power even when using an external 9V power supply.

• Deep, Lush Chorus
  The WA-C1 Mod delivers lush midrange depth and detail associated with proper Bucket Brigade Device analog chorus pedals. Leveraging a modern MN3007 BBD chip recreation with other premium components and boutique build quality, WA-C1 Mod is carefully clocked to match the depth and rate of the original pedal to reproduce the detail expected from the most sought after vintage pieces. 

• Rich, Three-Dimensional Vibrato
  When it’s really time to wobble, engage the vibrato setting for added speed and bounce to your tone. Experimenting with the vibrato side yields rotary-like modulation tones perfect for funk, fusion, blues, jazz and more. WA-C1 Mod adds a flashing LED for effect monitoring on the face showing which setting is engaged along with the rate of the modulation. 

• Separate Depth & Rate Controls For Chorus
  The WA-C1 Mod has separate depth and rate controls vs. the vintage “intensity” control. On vintage units, “intensity” increased only the rate as the depth was fixed, with the WA-C1 Mod, you can go beyond the limitations of vintage pedals by dialing in more subtle depth and variable rates for a larger palette of chorus tones. 

• Selectable Impedance For Multiple Sources
  The WA-C1 Mod has selectable impedance on the back panel to select between the vintage input impedance of 50k ohm and a 1.1M Hi-Z setting better suited for passive string instruments to bring out clarity. This switch works in bypass mode to maintain clarity while the pedal is not in-use.  

• Hand-Tested In Austin, TX
  Like all Warm Audio gear, the WA-C1 Mod has a 5-year warranty, and is meticulously hand-tested and inspected by trained technicians with a passion for making music in Austin, TX USA.

Deeper, Richer, Bigger: Chorus & Vibrato Tone
WA-C1 Mod delivers the lauded tones of the vintage Bucket Brigade analog chorus, the features of the Warm WA-C1, and updated pedalboard-friendly features - in one box! While vintage designs tied intensity to LFO speed and BBD delay time, the WA-C1 Mod adds independent depth control for everything from subtle modulation to lush, sweeping chorus. The Vintage/Modern switch engages or bypasses the analog preamp for classic vintage character or cleaner, more modern chorus tones. Engaging Hi-Z shifts the character from 70s warmth to a brighter 80s color with added upper-mids and treble, while the High input sensitivity setting adds headroom and clarity. A flashing LED provides visual effect and modulation-rate monitoring. WA-C1 Mod is 100% analog and built with premium components, including a premium Xvive MN3007 BBD chip. Compared to the WA-C1, the WA-C1 Mod adds top-mounted jacks and a vintage/modern switch that makes the vintage preamp bypassable.

Custom Enclosure & Premium Xvive MN3007 BBD Chip
The WA-C1 Mod enclosure is custom and finished in a rugged exterior with carefully tapered knobs. The enclosure is significantly slimmed-down and uses top-mounted jacks for ultimate pedalboard flexibility. Leveraging a premium, Xvive MN3007 BBD chip recreation as the centerpiece to the circuit’s modulation, WA-C1 is carefully clocked to match the depth and rate of the original pedal to reproduce the detail expected from the most sought after vintage pieces. 

Pure Analog Preamp with Modern Power Specs
The WA-C1 Mod features a 100% analog preamp matched to the renowned original, adding bite, depth, and natural harmonic content to guitar tones, even when the effect is bypassed. The new Vintage/Modern switch lets players preserve this classic preamp character or bypass the preamp entirely for easier gain staging on larger pedalboards. Internally, a dual DC-DC voltage converter provides robust power to the entire circuit, even when using an external 9V power supply.

Hand-Tested & Inspected In Austin, TX USA
Every single WA-C1 Mod is backed by a 5-Year warranty, and meticulously hand-inspected at Warm HQ in Austin,TX by real musicians and engineers with a passion for superior sound.
