I've never owned a push/pull pot before and I think that the one in my KM7 is faulty. I noticed the first few days after I got it that the signal cut out a few times when adjusting the volume but I didn't really notice it again for a week or so later. Today I was playing with the push/pull on the guitar and noticed that at one point when the pickup was split that it got really noisy and then the pot became REALLY sensitive to the cutting in and out problem. Here is a video of the problem.

The post seems loose and has a noticeable amount of wiggle. The pot doesn't jiggle, just the post inside it. Is this a "thing" for push/pulls? Do the posts usually wiggle in the pot or are they usually solid and just go up and down with no side to side?
On the flip side I'm pretty good with soldering and the solder job itself looks good. If I end up going to the trouble to re solder all the connections I want to just go ahead and replace the pot while I'm at it. Does anyone have any suggestions for best push/pull pots? Brands?
Sounds like a bad component to me. If it's a brand-new guitar, that should be covered under warranty.
