I tested this pickup through several guitars: an Epiphone Ultra II with chambered body, two Gibson Les Pauls, a PRS Custom 22, a knockoff PRS copy with maple neck, ebony fretboard and 24 frets, a sterling JP guitar.
This pickup is rock and raunchy. You can't get lost in a mix with this tone monster. Bass are tight because the fundamental frequencies are shifted to the high-mids.
This pickup requires a very bass-heavy guitar such as mahogany singlecuts. Mids are pretty scooped and handles low tunings very well. However, cleans are not the best thing in the world, and rolling down the volume only gives a spanky clean, similar to the telecaster bridge pickup, but with less picking dynamics.
Take care when installing this, as the pickup is really high in height, and it won't fit in smaller-body pickup routes (I had problem with superstrats).
