I got a surprise when I installed a SFII in my SJ5XXX yesterday. A little background, I ordered it in Dec 2015, received it July 2016. The only change I made was to rewire the bridge and middle PUP to get middle solo instead of the bridge. I got 2 Ptone PUPs and the SFII to better suit my Hard Rock band (the SJ5XXX worked great for my Classic Country band which disbanded upon the bandleader's death). I was looking for more low mids, hence the PUP changes.
Pulling the PUPs, I found the neck PUP was already a Ptone, the other 2 were both FD3s. I had no idea Ptones existed in Jun 2016 (the date of the neck Ptone), nor that one came installed in Super 5s.
Also, the original PUPs had the large Dingwall lettering on the cover, the newer Ptone have a small Ptone logo in the corner, the SFII has no logo.
My initial listen was just to make sure all the wiring changes were solid, PUP adjustments later today.
