I am selling my vintage Polytone double bass pickup. Has hardly been used since its manufacture decades ago. Was once the in-demand pickup because it is easy to install and remove, it simply fits between the feet of the bridge. Includes two different size inserts, a carrying case, and the original instructions. Uses a 1/4 inch jack. Asking $75/obo I am in Pittsburgh but may be willing to ship. Feel free to PM or email nmbrowne (at) gmail (dotcom) for any reason. Best wishes!
