A detachable and portable top pickup for a musical stringed instrument, comprising a clamp having an open end for attaching a top pickup on a pickup holder to a section of a guitar and a connector coupling the top pickup to an elongated bar, the connector allowing the top pickup to slide along the length of the elongated bar. A second clamp can be used to attach to another section of the guitar to get a stronger and more balanced hold for the top pickup. The clamps allow the top pickup to be removed, transferred or reinstalled without causing any damage on the surface of the guitar.
