The SAX Set has an unmistakable Strat™ sound: bright, airy, with a rich bottom end. With internal shielding and a low impedance preamp, you get a virtually noiseless pickup without sacrificing a true single coil tone. The Alnico V bar magnets allow for the output to remain balanced during big string bends that makes for a beautifully articulate tone. The X series preamp gives the pickup a more dynamic range along with increased headroom while keeping the more traditional string-to-string balance. X series pickups also come with an Active Tone Control (VLPF) designed to roll-off (attenuate) high frequencies, similar to a typical passive tone control. The result is a noiseless single coil guitar pickup with a classic EMG sound that bridges the gap between active and passive.
