WOW!!My '97 Classic Plus is great. The previous owner installed a 57 Classic/57 Classic + set of pickups and my tech swapped in a set of A3 magnets on the neck pickup and it sounds great. The neck is perfect for my hand. It's one of the best LPs I've ever played.
Beautiful guitar! Yours looks a lot like mine but mine is just a Classic Plus, not Premium Plus so your flames are a lot tighter and perfectly bookmatched. Very nice!
Here's my '97 LP Classic Plus.
The 496R & 500T pickups can sound great in the right guitar but terrible in the wrong one. They sound wonderful in my LP Jr. Special Plus but not so good in my son's Les Paul Studio.
For a Classic Plus, that still a killer looking top, even if it wasn't designated a Premium Plus.
I'm SURE I could install a much better pair of Humbuckers in my guitar, but I really want it to exist in its original form.
I'm going to accept that it has some very hot pickups, and the tones lead more toward hard rock and metal.
I've got several other LP's that scratch the lighter classic rock tones, so I'm OK with that.
By the way, for being just a studio, your son's guitar has a great looking top.
