The Tone Zone S brings the famous performance of The Tone Zone to a humbucking Strat replacement pickup. We've built in the tremendous mid-range and bass response of the original Tone Zone, and the same patented dual-resonance design produces great harmonics. We also took into account the likelihood of installing The Tone Zone S in the classic slanted Strat bridge position, warming up the higher frequencies and brightening the low notes a little. It has 4-conductor wiring for parallel humbucking and split-coil modes, and makes a great bridge position combination with the Pro Track, Chopper and Fast Track 1.
