Not sure if you're joking...
If you've followed my posts, you'd see I don't "follow" the JEM mythology, because I can't play them. I think they are awesome guitars, and I am a huge fan of Vai, but I can't play the things. So no- I'm not joking in that I don't know the complete "Mythology and History of JEM" lol
Way back when, in my hard rock days, a bandmate had one of the very first neon green JEMs, signed by Steve. I didn't like it back then. I forgot about JEMs (but not Steve) until recently, when I ran across a JEM woody, which I thought was a gorgeous instrument. Tried it- nope, still can't play the thing LOL. Those necks are like 1x4's... VERY flat and VERY wide. I prefer Fender and Charvel/Jackson neck profiles. If I could get a PIA with MY neck profile, I would.
