This is the clearest pickup I've ever played through. The sound is warm but not dark, bright but not harsh. It's a very controlled sound.
Chet Atkins liked Supertrons, saying that they "have more note". That is a very accurate way to describe the nature of the Supertron. It is not thin, in any sense of the word, but the highs are strong and clear. The lows are powerful and gutsy. I use this for Instrumental Rock; think Duane Eddy, Hank Marvin and Surf Music. It's the perfect pickup for this music. Likewise, it's great for Country, think Tele.
