You know what? The problem wasn't the potentiometer/dataknob...
I did some intensive repair on my An1x tonight, I'm the one with the
data kno values going awry and not responding (and sometimes Knob 4
values would pop up on the LCD even if I'm not touching it! Annoying
during gigs!!!) I'm sure some of you might have had something similar.

The problem is this: WEAK SOLDER JOINTS! Each row of knobs is a small
PC board and the eight pots are soldered to them. Well, on my faulty
Knob 4, I took a soldering iron and some solder and re-heated the
points, and added a little more new solder for good measure.

The knob goes back to normal! My AN1x works just like new now!

If anyone wants a step-by-step procedure, let me know and I'll post it
on the list or upload diagrams to the files section.
