Re: 59 Birdge in the neck
The '59B is exactly like a stock '59 or '60 Gibson paf. In those days Gibson would have used the same pickup as the neck pickup as they used for the bridge pickup...they were not calibrated.
The 59N is an underwound version of the stock '59 or '60 Gibson paf.
Personally, I'd go with the neck version of 59, or the Jazz neck or the Pearly Gates neck. Unless you play with distortion all the time...then go ahead and use the hotter 59B or Jazz B.
