        It sounds like the pot has gone bad.  The same thing happened on my
JamMan.  I e-mailed Lexicon, and they will fix the unit for a flat rate of
$95, or send you a replacement pot for about ten bucks.
       FWIW, I understand Lexicon is fully aware that a certain pot put on
some of their equipment is prone to failure and they've since changed
vendors for the part.  Once that warranty expires, however, you're outta
luck, and you must foot the bill yourself for a part known by the
manufacturer to be junk.  Caveat Emptor.
