Alan Entwistle HDN Neck Pickup.
HDN, or High-Definition Neodymium, was Entwistle's first neodymium pickup, and in fact one of the very first neodymium pickups in the world. High in output, but with definition that is razor sharp- so much so, that some active pickup users have changed over to using the HDN. It really is “Power with Tone”.  Zebra.  Neck DCR:  9.6K.  Neck Pole Spacing:  50mm.
Springs, screws and wiring diagram included.  Free USA Shipping.
