GIBSON GUITAR LAYOUTS

On a 3 pickup Gibson SG guitar, what is the function of each knob?
On a 3 pickup Gibson SG guitar, what is the function of each knob? I think the model is an SG – 400 (actually it is an Epiphone remake). I’ve checked the Gibson page, and the mention the standard layout, and 3 knob layout, but alas, not 3 pickup.
…Actually the guitar has 4 knobs. I understand on a 2 pickup it would have 2 volume, 2 tone (for each pickup). Not sure how this works with 4 knobs though. Oh, and the switch is a 3 way.
Thks
it will have a 3 way switch . one way for the bridge pickup , middle for all 3 and the other way for the neck pickup. the knobs are one volume and one tone and they adjust in the same way the switch work. one for the bridge and the other for the neck.
