This little guy replaced the super iconic CE-2 in 1982. This particular example was made but a few months later in 1983. The biggest difference is the handy stereo switching; this will do wet/dry or true stereo chorus. It's a tasty, wobbly vintage chorus with a lot to love, plus you needn't shell out the dollars the CE1 or 2 are commanding.
