What does it sound like in stereo? You can also 'trick' the pedal to do vibrato also. Put it on Mode II and put an empty jack in B and the regular A is output
Vibrato sounds okay. Not very fast, but for chorus, I like that. Stereo is decent. Haven't compared it with anything though so I really can't tell you what a nice stereo chorus sounds like.
How would changing the CE-3 input caps/resistors to the CE-2 spec input caps/resistors change the tone?
And nathanscribe, you said a straight swap of the IC's is not possible. I had a nice look at the schematic, and they look like they are all connected to similiar parts and have similiar value of resistors/caps coming out of the similiar parts. What makes them not compatible?
