I have decided it is time to upgrade from my RG170 to something better.
I play a lot of different styles of music from Pantera to Muse.
I was thinking of getting a Fender Mex Fat Strat with Floyd Rose and upgrading the pickups to the EMG SA/SA/81 set (all up comes to about $1200AUD).

Does this sound appropriate or is it a waste of money?
really since you have that kind of a budget, i would say that it would be good, but when you show up to buy the guitar try out everything that u were considering before that, what ive found is that my gut instinct is usually right
