The first new 9-Series model in 20 years, the CS-9 Stereo Chorus Pro offers dramatic improvements over the original CS-9. In addition to Rate and Depth controls, the CS-9 Pro features Delay Time and Dry Blend controls for limitless tonal options. Improved construction including through-hole, glass reinforced epoxy PCB's, snap-in PCB connectors, and true bypass switching guarantee trouble free performance while the combination of one Panasonic MN3207 BBD IC and one Signetics NE570 compander provides warm yet crystal-clear chorus with zero clock noise.
