This is a handmade pickup for my double bass. It's the type that goes under the bridge on the low-string side. Compared to copper foil types, it has less low-end push, but I think it's clearer as a result. Since the body is made of maple, the load on the top plate is less than with copper foil types. Please secure it to the tailpiece with the included cable ties, etc., and use it. It's new, only tested for operation, but it has a handmade feel. Thank you.
