Product Overwiew
Thank you for choosing an Onerr product.
The Nitrogen Chorus NC-1 electronically creates a mild
variation in the tuning of the instrument. You can mix it
with an original sound, which produces deep, subtle
tones. The NC-1 is also great for clean tones and when
you interact the delay, it provides keyboard-like tones.
