I had fighting faders for years with my Icon. Nothing would fix the problem. Tried earth ground, carefully cleaned over and over again even though they didn't even appear to be at all dirty, cycled, basically tried everything posted about the issue. Anywhere from 2 to 7 faders were always unresponsive to touch.
Finally had a tech friend out who figured out how to fix it.
He can be contacted directly at
[email protected] or call him (Lou DePasqua) at Innovative Technologies Corporation 847-877-1739. He's been doing music equipment repairs product designing in the Chicago area for 30 years. He's a good reasonable guy not out to rip anyone off.
He can provide you with a quote based upon the number of faders you want modified. You can send your faders in directly to him and he will turn them around quickly.
I haven't had one problem with faders since!
