I've been playing guitars all my life, have a Fender Strat vintage, great guitar, and an Ibanez Jem 77, a very nice guitar too, and played Takamines and Yamahas, but this Gibson Les Paul custom is something else. Great sound, huge sustain.
A bit heavy, but you can't have proper sustain without a dense body.
Playability 5 stars too, meaning, great fretboard. Precisely tuned.
Downside - none.
