All Other Guitars (including Prestige)
The QM pickups in my S540 always impress me, each time. Something about them is just pure magic. No clue what it is. I have Dimarzios , Duncans from the early 90ties, PRS pickups, etc., but the QMs in the 540er are just a great versatile set. Great.
But: there's barely any info out there...
