It's coming close to the holidays and I'll be getting gifts (mostly of cash and the like from relatives) and have decided that I want to get a new piece of gear.
I currently have a Schecter damien fr and a Peavey Vypyr 75.

I have been playing for about 5 years now and feel as though I have grown out of my gear and would like to find my own tone. I'm tired of modeling amps and am rather tired of my EMG's.

I have decided that my next amp is going to be a mesa mark IV (mostly because it's chepaer than the MK V) but havent decided on what to get first.

My question is this: since I am trying to find my own tone and improve my gear would it be better to get a new amp first of new guitar first?

Thanks in advance, and I hope this is in the right forum.
Amp. Always the amp. Going from a Vypyr to a Mark IV as you plan will be a phenomenal improvement.
