I stumbled across this forum because I wanted to see if there exists any other form of hollow body SG. I own a 1999 Gibson SG special (modified with a P 94 R & a Seymour Duncan P Rail T pickups). The thing screams, and played like a dream. Sadly, like many other SG's, the neck snapped when it took a bad fall. I got it fixed but the intonation was never really the same. So I decided to bite the bullet and have my own custom guitar built.
The thought of designing a hollow body SG had been on my mind for years and while it might be sacrilegious to the SG or "solid guitar" community, I decided to bite the bullet and bring my design to life. I got in touch with Chris at Highline guitars in CO and he built my guitar for me.
The body is 2 1/2" thick (yeah I know, "that's nuts kid") with solid mahogany back, sides & neck, a flame maple top, and a Bolivian Rosewood tailpiece & 24 fret fingerboard. The pick ups are custom wound, similar to PAFs, with a coil splitting option for each. The tone is amazing. It can sound like an acoustic guitar and then with a flip of a switch, combined with a Maxon compressor and two tube screamers, it produces the best sustained overdrive tone I've ever experienced with any of my guitars, or others I've played.
I'm sure that diehard SG fans will scoff at this guitar, "because one shouldn't tinker with an iconic design" but I'm a diehard SG fan (it's the only electric style I'll own) and my hollow SG takes my tone to the next level.
