I was wondering, with vintage handwound pickups, people say that if the middle pickup isnt reverse wound or something then there'll be the usual hum when you're near like neon lights computers and stuff. Can this be eliminated using a noise gate pedal (like the MXR Smart Gate) ? thanks
If set correctly then yea a noise gate should work. If not look into a volume pedal

For a second i was worried you actually wanted to add pickup noise...too much of this vintage crap lately
