Koldwave Analog Chorus

Koldwave Analog Chorus and Vibrato

How do you improve on an iconic pedal like the Boss CE-2 chorus? It’s always been my favourite chorus pedal. This was the challenge I gave myself. After a year of tinkering and countless revisions and roadblocks, I’m super excited to share the result with you.

All those classic 80s lush chorus sounds we love are in there. But I wanted to add more functionality, range and features. I gave it a little more depth and speed than the classic CE-2 circuit. Now with the speed knob fully clockwise it can do the rotary speaker thing. I added a vibrato mode as well and I’m really happy with how that turned out. It gives you all the lo-fi, warped vinyl, seasick sounds you could want. The warp knob is the secret weapon and gets you those super detuned rubber band sounds as well.

I also made it true-bypass unlike the original. And most importantly, I reworked the preamp and the eq filtering in the circuit to really bring the CE-2 circuit to life. My 1980 CE-2 sounds like it has a blanket over the amp next to the Koldwave. I removed a lot of the CE-2 muddiness, giving it more of a “3D” tone. I’m very happy to say the least. Needless to say, my old CE-2 will be collecting dust on the shelf now. It was my favourite chorus pedal. 

Features:

  • Fully analog circuitry with BBD chipset
  • True bypass with relay soft touch footswitch
  • Runs on standard 9V Boss style power only (standard 100mA)
  • Designed, backed and built in Canada with love
  • Please note: Vintage-style BBD chorus pedals are designed to work best with passive pickups/electronics.
    Hot-output instruments might clip the pedal's input depending on your settings.

Chorus 101 5 product stars
"Man this thing is the best. The variety alone on this pedal sets it so far apart from all other options out there, and it looks great too. The amp and frequency knobs give so much control that I didn't even know I was looking for. Special mention to the Vibrato section also and the rotary setting with the speed all the way up. From ordering to plugging this in, the whole experience was perfect. Freqscene is doing it best!" Graham - Wednesday, September 2, 2026

"This thing is perfect. I've never felt super comfortable with any chorus pedal I've had on my board. Koldwave does it all. Having the Vibrato swtich is a great feature and the boost is a great touch." Matt T - Saturday, September 27, 2025

"The coolest, smoothest, prettiest, and most versatile chorus! Special attention to the warp control to give the sound a fantastic sense of depth to the sound, as if everything that came before was flat by comparison. It s incredible fun to be able to get all my favourite chorus sounds from just one pedal, and the extra bonus of a volume control to balance it according to the headroom of your amp. And that s not even mentioning the vibrato mode that, thanks to the freq control, instantly became my favourite vibrato so far!" 655321 - Friday, February 28, 2025

"It just sounds fantastic. The vibrato setting is also a super welcome addition. The warp feature is really cool and the frequency and amp settings give a lot of control over the tone. It's just wonderful." Layton - Friday, February 28, 2025
