Tried 'em and hated them!
The bottom string was way too big for the nut, which I had to adjust to compensate, I'm normaly a 9 or 10 guy. When I got them on I had to re-adjust the string height etc as the extra pull on the neck was way too much, and after all that they just felt fucking awfull!

kinda like playing a bass! The harmonics are so much harder (nearly bloody impossible) to get out of the bottom string and it just felt so tight, even when tuned way down.
Do yourself a favour and go for some ernie ball hybrids or similar if your after a chunkier low end. I dont know how even Zakk could play these things comfortably let alone anyone else........oh, but its got his name on so it must be good.......bollocks!!!
