Here's what you don't what it to look like...
it's a little hard to see but if you look closely, the bridge poles aren't lined up with the strings but yet they are on the poles on the middle pick up's poles.
I have to confess that I can't tell if there's any impact on the sound, to me it sounds fabulous in all pup configurations. Also as the photo shows you have to get right up to the guitar to see that there is anything amiss. The Dimarzio's are so hot that it pick's up everything just fine. That said, get a matching pair!
