Wow! Some guys in here are a little heavy handed w/ their opines. Yeesh here's my .02 on a scale of 1 - 10. 1 being the avg. beginner setup and 10 being the avg. gigging guys setup. I give it a 7.
Things I would change.
The only things I would change here is some modifications to the strat. A new set of pickups, new wiring harness, Callaham block & saddles and you're golden. I don't care how much Fender says the new strats are ''improved" they're still using run of the mill pickups and a zinc alloy block...only bigger. You sink the 2 bills into you're strat and I GUARANTEE you'll hear a major difference in that guitar.
Amp. I'm not going to complain a lot here where some do. I will reiterate a new cab preferabley w/ a Vintage 30 - Greenback mix of speakers. And a new set of tubes. That usually does the trick for any PV amp and the Windsors are good classic sounding amps.
As far as tonal Versatility....If you use alot of cleans in you're music, leave the amp set to clean and get accquire yourself a few good dirt boxes to throw in front. Then you're only limited by how many stomps you can buy.
Set the ME 50 for delays and such and leave it in the loop...
The wah? I say gut it and drop some new innards in it. Usually cheaper than buying a new high end wah. There's a few places you can buy wah kits from Area 51 audio gets high reviews on there's and it's only $90 if I remember correctly.
Other than those few things, I'd say you're golden.
