I played around for about 30min last night... guitar > OCD (v1.4) > MXR CC and everything seemed fine. Even tried two amps - Marshall Class 5 and my Jet City 20... seemed normal. I run the tone on the OCD at about 10-11 o clock and the volume at about the same. MXR settings are very low as well. I played several things and all seemed to work okay with or without the pedals engaged together or alone.
When I reversed the order it got crazy though. MXR CC > OCD is crazy sounding because all the echos get touched by the OCD differently it seems. Cool but not useful for most playing.
I'll keep playing with it to see if I can replicate the issue mentioned, but so far... works fine.
