Ok so normally I'm into metal when it comes to playing guitar but recently I have gotten really into Phish and I love Trey's tones but I looked his gear up and since his guitars are custom built by a small company they alone cost at least $10,000 each, so I'm looking for some more affordable alternatives preferably around $1000 for a new guitar and amp each if I need to get a new amp as well.

How should I update my gear(which is in my signature) to get a good Phish sound?
