This is an amazing stereo chorus very rare and hard to find. It's a collector's item on top of a great sounding chorus. Made in the 1980's the pastel lilac‑coloured CS9 Stereo Chorus was made in Japan for Ibanez by business partner Maxon between 1982 and 1984. Very warm sounding and highlighting some sounds and chords as it was used by Nirvana.
