The Revel J-90 combines the very narrow coil of a vintage Jazzmaster pickup with the adjustable poles and dual magnets of a P-90.
Wound with plain enamel wire, the bridge uses a combination of rough cast Alnico V and Alnico II while the neck uses Alnico V.
It’s a very unique tone. They are focused and exhibit good string separation. They are jangly but with P90 grit and mids. They are bright and clear, overdrive easy, and have solid bottom end.
If you’re looking for a pickup that will help your Jazzmaster and your tone stand apart, look no further.
