The new and improved "El Sensor" has been updated with dramatic new looks, greater output and expanded harmonic range. Designed by Jeff Lace to embrace the Tejano, Tex-Mex and Conjunto styles of popular music, the El Sensor sounds as good as it looks. An enhanced magnetic field design allows the El Sensor to have balanced string output not only on a Bajo Sexto, but for a Bajo Quinto, too - This can't be done with other pickups. Unlike other pickups out there, the El Sensor is 100% USA made and uses our patented sensor design. The El Sensor will make you stand out in a crowd both musically and visually. The El Sensor is available with or without volume control and comes in a number of colors and styles. Our "El Sensor Imperial" uses gold plating. All models come with a female endpin jack.
