I have just purchased a USA Custom 24. First off, it did not come with a trem arm as it was not in the case for some reason. Then I noticed that the volume knob doe's not rotate straight. If you look at it from above you can see the shaft is not straight. It's not much but the tone control is perfect so I assume the volume pot should be the same. Lastly when I move the selector switch from position one to position two it pops. The rest of the positions are fine. I have found that when you start to move the selector switch the mechanism does not move until the lever gets to a certain point. The mechanism then flicks forward and hits the contacts which is amplified as a pop. I would have though that a $$$ guitar should have flawless electrics. Any advice would be greatly appreciated as I am not sure if these are design flaws or mine is just a bad example. Thanks for reading.
