Here's a pickup I made for my double bass. It's the type that goes under the low-E side of the bridge. It's a standard style, and I think it's easy to get a strong low-end sound, which is characteristic of a bass. It's new, only tested for functionality, and has a handmade feel. Please be careful not to cut your hand on the copper foil edges. Please use the included cable ties to secure it to the tailpiece. Thank you.
