The Seymour Duncan 11103-70-NC is a high-performance humbucker pickup specifically designed for use in the bridge position of electric guitars with tremolo systems. This TB-11 Custom Custom Trembucker model delivers a powerful, articulated sound with enhanced midrange presence and controlled bass response. The nickel cover gives the pickup a classic appearance while slightly smoothing the highs. With dimensions of approximately 89 mm in length, 38 mm in width, and 16 mm in height, it conforms to standard mounting sizes. The dual ceramic magnet construction produces high output with excellent string balance and harmonic clarity. With a typical DC resistance of about 14.7 kΩ and an inductance of approximately 4.2 H, this pickup offers a balanced frequency response suitable for various music styles from hard rock to blues. The four-conductor wiring allows for multiple installation options, including series, parallel, and coil-split configurations. Stability and reliability are ensured by the precisely wound coil, wax potting to prevent microphonic feedback, and a robust construction that withstands demanding playing conditions. The nickel-plated pole pieces and baseplate contribute to the characteristic tonal properties while providing corrosion resistance. Compatible with most electric guitars featuring tremolo bridge systems, this pickup delivers consistent performance with excellent sustain and dynamic responsiveness. Installation requires standard humbucker routing and standard electronic components.
