IIRC, Paul used his favorite real '58 Gibson Les Paul's as the basis for the original '70s PS. They really feel and play close to a Les Paul without the weight.
Been on the SG train lately too. Just grabbed these two (and the blue one is new new). Both have Wagner Godwoods in them now. I didn’t love the stock pickups in either for my tastes. They hang out with my '94 Standard and my Jaydee Old Boy.
