The original neck pickup in my 1983 Hamer Blitz turned completely to mud a few months back, so I decided to replace it.  After listening to samples on the Seymour Duncan website and reading the various descriptions, I chose the SH-2 Jazz.  I couldn't be happier with my choice.  As described, the Jazz has a "moderate output" and an "articulate and clear tone".  Chords have definition and clarity I was definitely lacking with my previous pickup, even before it went south on me.  In my opinion, the Jazz is a great pickup because it really lets the character of my guitar shine through.  I wish I had changed pickups years ago, as I feel like this guitar is finally living up to its potential.  It has always sounded so warm and resonant when played acoustic and with the Jazz in place, I'm finally getting that same vibe amplified.  Well done Seymour Duncan!
