Is your setup so unique/special that you can't play your mates guitars?

No, I can play any guitar with any action or reasonable string gauge. Scale length, set up or neck profile doesn't much matter to me.

I can play "chemical warfare" on any guitar.

Not so much....any guitar I pick up, I still sound like sh*t!
Working on changing that though.
Seriously though...I know the ESP/LTD's played very nice as well as the Ibanez 570's & 550's. I can diffenitely tell a difference in quailty and it does make playing so much easier.
