It is a versatile pickup, excellent for all my styles of play. If you ever find one of these, buy it. It really IS that good. I was always happy with it with my BF'ed '75 Pro Reverb. That was a bright amp and the HFS was punchy with moderate to high gain.
Lead sounds soar but also bark.
A somewhat creamy sound but has a good midrangey bite instead of a trebley one. Excellent for all rock. Not a clean p.u. Rich, creamy overdriven chords. Punchy, talkative, smothly articulate leads.
