Yea JCM 800 is a badass amp, vintage 30's are real good speakers. If anything, i wouldnt suggest having the same ones but fiddle around these, zakk wyldes settings are Zakk Wylde Settings
Bass - 10
Mid - 4-6
Treble - 4-6
Presence - 2
Master - 4-6
I always believe in your own sound but this is a base. I have my treble at 6 and bass at 6 and have mids like at 4 and its not a bad combination i get that nice bite.
