If you want the 1984 tone, get a keyboard. As far as I'm concerned, 1984 was their weakest (except maybe DD) album for guitar playing. Hot For Teacher and Panama were both cool songs, but George Lynch showed Eddie up on his version of Panama on the VH tribute album. Not to say that Lynch is a better guitarist. 99 times out of 100 Eddie would do better, it's just that 1984 was his way of showing DLR and the rest of the world that he could put out a successful album with keyboarding. DLR never liked the idea, and it was probably Eddie's way of saying I'm the one in charge and if you don't like it you can leave. We all know what the result was.
If you really want to exactly copy Eddies guitar sound, you have to figure out which guitar he was playing on that particular song. Part of the reason for telling so many different stories (along with him not wanting people to copy him) was that he used a different guitar on almost every song, and there's no way he could remember what pickup was in each guitar. I mean, the man had hundreds of guitars that he had modded in his own way. I'm sure all those pickups are good choices, because he probably used them in at least one of his guitars. You also have to remember he's a big fan of Korina which he used on many occasions, and that can make a BIG difference.
But then you have to consider what GearJoneser said, and he's exactly right. Ted Nugent played through Eddies equipment exactly like it was set up to go on stage. Ted is a GREAT guitarist, and he didn't sound like Eddie. You have to have the chops, the feeling, and everything else to pull off an exact copy. There are a few that can, but most are satisfied with sounding pretty close. Just get you a 59, a JB, or a similar pickup. You'll get close, especially after you throw the effects in with it.
Remember, he used a Floyd Rose live, but never used it in the studio because he thought it was too bright (probably so). That's another factor you should consider.
Whatever you decide, just have fun!!! That was one of the biggest parts of his playing. That's all he wanted to do is play guitar. I'm just glad he traded instruments with Alex!
