The low end hits with punch and intention.

On a clean channel, the neck opens up with a glassy chime that stays controlled and musical.

On the Seymour Duncan Whole Lotta Humbucker (SH-18)

With similar push and drive as the 59 Model set, the Whole Lotta Humbucker is a little more articulate in the lows and a little tastier in the highs.

There is a really nice balance to the set, compliments of a slight snarl in the mids.
