A clip is worth 1000 of my crazy posts!
The only drawback of P-90s is that with lighting dimmers, appliances, breaker boxes and monitors, etc., in various places in a building generating electromagnetic interference, you sometimes have to turn in a circle to find a spot that isn't noisy. That doesn't bother me, I can always find that spot, but it's good to be aware of it.
If the guitar gets noisy, just turn a few degrees to the right or left, and bingo, you're in a quiet zone.
It's good to have a guitar with Soapbars - people obsess over small differences between PRSes that are actually kind of hard to distinguish, at least to the listener, but one with Soapbar pickups is going to be that much more different than some other choices.
