Today, the pitch on my Claravox was jumping uncontrollably making it so I could not play during my lesson. Swapped out to my e-pro.I sent a recap and attached a video to MOOG. So frustrating.
Have you resolved this problem? Mine does the same thing intermittently. Also get the popping sound on the volume antenna when touching it just like the EWS. Also the volume antenna does not mute completely when my fingers are through the loop as others have mentioned.
BTW I have lovely #411.
