The pick-ups are further evidence of PRS's (and their dealers, in this case guitar center) total commitment to customer service/satisfaction. They are "on loan" from another PS build I have in the works. These and the 85/15's are now available for order with PS builds (I've seen at least one other guitar on here with them). I have no info on which, if any, non-PS models they will be available for. I have heard...third hand rumor...that the 58/15's will be the "standard" PU for the PS McSC next year. I'll find a "worthy victim" for the transplant and try to report back.
