Re: how will these sound
Hey Mitch, I have ex-inlaws in Davison but I won't hold it against you!
The DDn (103n) is a cool pickup and if you like the tone for the moment then keep it. I have a Les Paul with a Distortion set and I really dig the tones I get from the DDn. Balance-wise, the DDn is probably better suited for the Custom series, JB, Distortion or any of the 14k and up pickups but that doesn't mean it wont work for you with a PG or 59 in the bridge.
You just have to try it and see.
