This is a guitar i'm thinking about buying:
http://www.guitarcenter.com/shop/product/Gretsch-Guitars-G5120-Electromatic-Hollow-Body-Electric-Guitar-with-DualCoil-Pickups?full_sku=103867990

It says it has 2 dual coil pickups. So what are dual coil pickups and are they good? I know of single coil and humbucker and all of them but never heard of dual coil.

Probably just means humbucker, because that's essentially what a humbucker is - a pickup with 2 opposite polarity coils.

Yeah... Dual-coil = humbucker.
