I had a 1984(5?) CE-3 and found it to be slightly metallic sounding. Mind you, I didn't have a chance to try it on a really nice amp. I will say, however, that if you turn the mode switch to the right, you actually get a pretty nice vibrato mode, if you're playing in mono. That alone may be worth the small price of admission.Could you elaborate more on CE-3?
Last year I hunted down a new chorus. I've owned a CE-3, CE-20, CH-1, and compared the CE-2w, MXR Analog Chorus, SD Catalina, and Strymon Ola, and the Ola won by a landslide. I didn't expect to like it at all, and initially planned on buying the CE-2w, but the sound is undeniable. If you can try one, hop on it. Even Strymon diehards seem to be sleeping on this one.
