The Air Norton S™ is the Strat® replacement version of the full-size Air Norton™ humbucker pickup. It's warm sounding, very well balanced, and has the same unique tonal characteristics as the original. The original Air Norton™ wasn't designed for a specific position or type of guitar, but it has become most popular in the neck position of trem-equipped guitars for progressive music. (Thanks, John!) The S version is also a very good bridge pickup for all types of rock. Its combination of medium output and harmonic bite are very effective for single-note soloing as well as chords.
The original Airbucker™ pickups have an air gap between the magnet and the pole pieces. The Air Norton S™ doesn't have this feature, but the sound, output and feel are so similar to the original that DiMarzio couldn't call it anything else. It's very good in the neck position with The Tone Zone® S or Super Distortion® S in the bridge, or in the bridge position with a Pro Track™ or The Chopper™ in the neck. We like The Cruiser® or Fast Track 1™ in the middle with either setup for brighter sounds in the 2, 3, and 4 positions.
