The same patented dual-resonance design used in The Tone Zone delivers a sound that's hotter and bigger than any vintage model, but not as loud as a distortion-class humbucker. Norton might be DiMarzio's most versatile bridge pickup. Combine it with a wide choice of neck pickups like the Air Classic, PAF, PAF Pro and Air Norton. Tech Talk: Norton was originally designed to extend the tonal range and power of standard output humbuckers without going over the top. It's more modern than a PAF sound: the benchmark Les Paul/Marshall combination yields more midrange crunch and high frequency pick harmonics than vintage-style pickups were capable of putting out. Really good for opening up the sound of mahogany set-neck guitars.
