Hi,
I just picked up one of the 60's tributes and it's very nice.
Aside from the neck, the other difference is the electronics -- the 60's doesn't have the orange drop capacitors. It just has these regular small ones. And the cavity cover isn't see-thru. I may put them in, but I'm not unhappy with the sound.
Still, I really like the guitar. It's taken a little getting used to because I usually don't play a barely finished neck and the fret shape is a little square for me, but it has been worth it. The sound and weight relief aspects are amazing -- it's hard to put it down. P90's are my favorite pickups by far -- woody, crunchy, live, airy ... they have it all.
