That's what put me off, call me old fashioned but I don't like writing on my pup covers. Changing them isn't an issue unless, like the GZR's, the pups covers are none removable. Ive just swapped out a set of SPB1's from my MIM 50's and have gone with my usual pups - Pribora Handwound. All my P basses have these in, they are a lovely trad style pup
