Thanks for reply, and sorry to hear about your buddy. After research I've decided to leave this limited edition alone and go for a standard LP. Seems this middle PU can be intrusive to playing, and in most cases not necessary.Never played one but a buddy of mine (who sadly has passed on) had one years ago. It was his backup to a 3PU Black Beauty that was his "number" one. Played mainly blues and dabbled in jazz.
IIRC, he liked a SD Jazz as the neck pickup but I don't remember if he swapped the others.
Good luck with your search for one.
