Gibson SB-300 and SB-400 single-coil pickup

This pickup was also used in the SG-100, SG-200, SG-250 and ES-320 guitars. Gibson part number 13570 (front and back pickups identical). Stylistically they borrow from the Les Paul low-impedance pickups used over the previous years: black plastic, with embossed Gibson logo, rounded ends with matching chrome plated mounting-ring.
