I've logged a support call, but thought I should check here as well.
The 4th knob under the display (the normal Presence control) is intermittent on whatever parameter it's adjusting. Sometimes I can turn it a quarter turn with no change to the display value, then all of a sudden it eventually jumps to the new value.
Example: Trying to adjust the Presence to zero, slightly turn the knob and nothing. Turn a bit more, nothing. Turn a bit more, jumps to -4. It's almost impossible with that pot to get a zero value because it jumps around. The other knobs track really smoothly.
Any of you experience this? Am I likely to lose my new KPA for a few months if I need it fixed?
