my current setup creates a bit of hum that i wanna try get rid of it.

my current setup is guitar (ltd kh-202) > wah (ibanez weeping demon) > distortion (boss mt-2) > amp (peavy bandit 112)

ive looked at the behringer fbq800 would that help? if i got it i would put it in my amps effects loop so i could control the preamp too?
It's more likely the amp or the pickups. Is the hum only when you're not touching the strings?
It could be the distortion. Sometimes being at such high gain creates hum. And honestly, how would an EQ help? look at a noise supressor/noise gate.
well a eq has different frequencies so i thought i could find that frequency thats causing the hum
