I am not ashamed to say I have/had no idea who Zakk Wylde is, my original thought was that it looked more like a Hitchcock Vertigo design, a couple of google searches later it turns out that was the original inspiration for his "1981 Gibson Les Paul Custom “The Grail” guitar:
Zakk bought this guitar upon joining Ozzy Osbourne band in 1987. He traded this guitar with Scott Quinn, who in exchange got a double neck Gibson SG.
When Zakk received the guitar, it was equipped with standard humbuckers, but Zakk very soon replaced them with EMG 81/85 set – after trying them out on one of his student’s guitar. Originally the guitar was finished in blonde/cream color (still visible on the sides and the back of the body). but Zakk felt this was Randy Rhoads’ signature thing, and he wanted something different – so he decided to send the guitar to a guitar luthier for a paintjob. The initial idea was to paint the Hitchcock Vertigo design on it, but the guitar came back with the bull’s-eye decals. Zakk ended up liking it, and he decided to just stuck with it.
Cool sketch !
