The Thunderbird is a classic body style and EMG offers direct replacement pickups for players looking to get more from their instrument. This dual mode pickup offers two unique tones. The single-coil mode is our JCS pickup built with ceramic magnets and steel pole pieces for a rich, warm tone. The humbucker mode is our popular CS (ceramic steel) dual-coil for a big, aggressive sound with a pronounced mid-range. A push/pull volume (or tone) pot allows you to change from the rich clarity of a J pickup sound to the fatness of the CS humbucker. Package includes: EMG'S EXCLUSIVE SOLDERLESS INSTALL SYSTEM: 1 25K VOLUME POT; 1 25K TONE POT; 1 BATTERY BUS; 1 STEREO OUTPUT JACK; 1 PAIR MOUNTING SCREWS; 1 PICKUP CABLE; 2 CONNECT CABLES; 1 OUTPUT CABLE; 1 BATTERY CABLE.
