So I finally appeased my GAS a bit, and found a used RG7321 for a song at swap shop, been wanting one since march. paid $225 for it, and you can barely tell its used.

Does anyone know if they are coil tapped stock? because this one is. I couldnt find anything online

secondly, what exactly is coil tapping, it splits the humbucker right? Because I notice on some settings it sounds very single coily
It has a five way switch right?
Position 1: neck humbucker
2: neck in parallel
3: neck and bridge
4: neck and bridge split, either the inner coils of the outer coils can't remember
5: bridge

2 and 4 should give you single coil like sounds
