The Super Distortion® is primarily a bridge position pickup, although it can be used in the neck position with a relatively low-gain amp. Specifically designed for solid-bodies: hollow and semi-hollow guitars can be hard to control with warm, high output pickups.
The Fast Track 1™ is hotter and more muscular than The Cruiser®, but it’s still very bright and clean sounding — not at all like a full-size humbucker.
