Rio Grande Pickups’ Vintage ’51 for P-Bass is a ’50s-style P-Bass design with four exposed/sand-cast Alnico V magnets and two-wire cabling. It uses “historic” vulcanized-fiber flatwork for period-correct styling and has either standard or vintage 22-gauge/seven-strand braided-cloth insulation. The company also offers the Muy Grande ’51 for P-Bass, with larger magnets. Visit www.riograndepickups.com.
