It's good to get a bit of variety in your gear, maybe get a cort or esp. It just seems a bit odd to me that anyone would have 4 ibanez guitars. Not that there's anything wrong with ibanez, I used to be a die hard ibanez fan myself. I just think that a little bit of change could be good.
As to what guitar to buy specifically, what price range are you looking at?
Stage fright...thats a trippy subject. What works for some people can really screw up others, and what doesn't work at all for some people may be a lifesaver for someone else. I would recommend just becoming more of a people person. Go out, make new friends, just become more comfortable around other people. Become friends with the type of person who wont think any less of you for royally screwing up on guitar.
How I myself got over stage fright is quite odd. I just woke up one day and was just struck by a revelation. It doesn't matter what a bunch of strangers think about your guitar playing. If they don't like it they can go f! themselves. I just out of the blue didn't care what anyone though anymore. I don't know how or why it happened, but the sudden apathy has saved me a lot of neurosis.
Just for memorys sake, that about the time I made that post about watching the jfk assasination. Anyone who read that post think that it might be more than coincidence? Just a question to make you all (and me) think.
