I play classic rock, and metallica, and thats pretty much it. stuff like van halen, guns n roses, led zeppelin, hendrix,and as i mentioned, metallica.
my rig(im not includng my crap guitars which i will never perform with):
fender mim strat fsr w/scn pickups/gold hardware
fender bues junior
digitech metal master
digitech delay
digitech synth wah(i have no idea why i have it)
digitech hendrix experience(not agree well at all with my tube amp, please help if you can)
boss dyna drive

my most used is by far the metal master, i cant really get good pinch harmonics with the boss, and van halen and gnr just sounds better with the metal master.
but what else do i need?
and im very aware of the fact i could use a metal guitar, but i dont think i can make such a big purcase at the moment
lose the auto-wah and get a Crybaby. i have the 535Q, it's an excellent wah pedal and probably one of the most versitile ones Dunlop makes so i'd stongly recommend it to you.
