The two weak links on the Vortex are the rotary encoder and the external power supply. One way to avoid wear and tear on the encoder is to use an external footswitch to change program values.

almost always the problem. I've had a couple repaired by Lexicon,
but I've also had them sent them to me and installed them myself
semi-successfully. (one screwup with overheating and destroying the
pot). I've had 6 or 7 Vortexes and one last one in my rack that
acts semi-weird and I'm really starting to become very of dealing with
them. Gotta find something new for parallel stereo tweakage!
