I have an Aria MAC57/7 (7 string).
Excuse the dust (the flash on the camera shows it up...)
It has a dual humbucker setup and a set of controls that I never fully got to grips with.
I assume the two black knobs are tone and volume and I understand that the black switch is a pickup selector, switching between the neck, bridge or both pickups.
It's mainly the two small, silver, two-way switches that are baffling me. They do have an effect on the sound of the guitar, but I'm not trained enough to understand fully what that effect is.
Could any shed light on what the other controls are?
