Default Lexicon LXP1 & LXP5 issues and troubles--15 years later

LXP-1. This is just a comment. Both the 1 and the 5 were known for having
scratchy pot problems. And they would make a frightening sound as a result.
I had it on my LXP1. I never bothered to fix it since I read in RAP that
this was more than a dirty pot problem--some said the pots had to be replaced
and others mentioned faulty caps or grounding issues. Well---I actually
took out the deoxit, cleaned them and presto---all good.



Oops! While searching google groups I found a post from myself stating
that I had, with success, cleaned the pots on my LXP-1---This was in '97
or so.


LXP5---A definite problem.



Why am I not using it, well---it has another kind of pot/knob problem.
The settings sometimes appear to jump around. It is as if the
"program", "select", and "adjust" pots are randomly shifting.
These three pots are controllers. Unlike the input, out, and mix knobs
which actually carry signal, these three change the programs. They are
sealed pots (so I can't spray them) and they are detented (no resistor
ladders, here). Has anyone ever had this problem and solved it?
Is it definitely the pots? Or are there some caps that could be affect
it? Years ago I could probably order a new set of pots from Lexicon,



Hey check this out (well only if you care about this problem...):

Now that's interesting. If that works, I can live with that. I found
another post where a studio simply removed the pots and programmed
only from an MRC.


But if use it for guitar, as you indicated you may, having to use the
MRC all the time may not be very practical on stage...
