I've had my Ibanez GRX40Z for almost a month now, and I know that the switch controls which pickups are being used (and I know which pickups they are thanks to the Ibanez website).

My question is, what are the difference between each of the pickups??

If you don't know the guitar in question, there are two straight pickups (one near the neck and one in the center of the sounding board), and two pickups that are attached and movable, pivoting between the two.

Thanks!
