For around a grand I built my #1. SE custom 24, locking tuners, Mann trem, USA nut, and Bare Knuckle Stormy Mondays. It is a very fine instrument. I am not sure a core would make $2500 happier.
My buddy, a gigging jazz player, used it for a gig and loved it. Believe me he’s played some guitars. His #1 is an old L-5 which is probably worth a fortune. He asked me to put a prs together for him.
I am sure S2s are fine instruments, but I’ve played tons of SEs and they are consistently great. My next axe will either be an SE 22 semi-hollow or an SE hollow body.
