Ive modded a metallic blue Indo crafted affinity P with new, electronics, pups, shielded cavity, ashtray, and parchment PG. I dont see the point in changing the output jack, bridge and tuners. My question is, whats the point in changing the neck? The affinity neck is nice and easy to play. I already have a MIA J with a maple neck, so I dont necessarily need one for the P, although I do think they look better. Whats the difference in the vintage modified, classic vibe, MIM neck? What would I gain by upgrading? One last question, wouldn't a pup cover get in the way?
