Cool looking guitar Matty, but personally, I'd put beefed up/hotter humbuckers in it myself, maybe with a coil tap switch for each pickup, but that's just me......It might also be cool to have a "kill switch" for each pickup, instead of the 3-way selector, that way you could get different pickup configurations that wouldn't be possible otherwise (IE: split the bridge into single coil, & select the "front" coil (toward the neck) & have the neck pickup split & select the coil toward the bridge.....with the 3 way switch, that' not possible, with the 2 "kill" switches & coil taps it is.......it'd kinda be like having 4 pickups that you could use/switch on/off, I had a late 80's model Ibanez that had 3 pickups (humbucker in the bridge, stacked humbuckers in the middle & neck, with 3 on/off "kill" switches. I was able to use the bridge pickup while using the neck, not possible with a regular 5 way (my guitar would have had a 5-way, where your SG has a 3-way....) switch...).....just my

Speaking of SG's,
this was my first electric guitar (well, one exactly like it, same color, same everything.....), my parents bought for me when I was about 13. Kept it for years, until my ex-wife decided to get rid of everything I owned (I mean
everything too....

), including a guitar like this, an old, old Fender tube amp, along with other "needless" things, like tv's, appliances, furniture, my clothes & such. Nothing I really "needed".....

Came in from work on night, & all I had left were literally the clothes on my back.....What a woman!!!! No wonder all the music I write/record sounds so angry & dark huh??? It's kinda funny now (in a way, but not really), but at the time, when I came in & saw what had happened (I knew it was coming, but never dreamed she'd take my music gear....), it was like the weight of the world had been lifted off my shoulders.....
Sorry to go off topic there man, cool guitar, I'm sure however you decide to hot-rod it will be killer!!!! I'd like to hear some "before & after" clips myself.......
