Ok, here's a spoiler of what's comming. I coudn't get my hands on quad gangers, so, I jerry rigged one from 2 dual gangers using a hex key. I noticed they have a hexagonal socket on backside, so, I cut a tiny piece out of a allen key, file one of the ends into a slot drive-like shape and got my quad ganger working, one spin controls the 4 of them pots. Those are for the volume, which I'm using a single control for the 4 channels. If I decide to use quad gangers for tone controls it'll be easier, cuz I can use the same method without haveing all the trouble of filing a hex key, I'll just arrange them back to back, once they are not log.
