K & K Sound Pickups: Pure MiniThe PURE MINI is a transducer system only. No battery, no onboard electronic, just the pickups. Don't be fooled by the sound of others' thin sounding passive systems. The Pure Systems are definitely different. They sound full and rich and have sufficient output to drive most amps and PA systems directly! Pure Western passive system for steel string guitar, three pickup heads, endpin jack. These work great for split saddle guitars too.
