I installed this in the neck of my Charvel ST Custom (Strat style - Ash body, Maple neck, Rosewood fretboard, 2 point non locking trem). I wanted something a little more powerful to replace the stock stacked single coil and also a pickup that could keep up with the Dimarzio Crunch Lab I have in the bridge of the guitar.
It really is a great partner for a high output pickup like the crunch lab - it means you can go from a high gain bridge rhythm sound to a smoother neck solo sound. It has a medium level output and quite a mid focused character that helps solos to stand out more, but also gives clean sounds a lot of depth. My favourite sound is clean with lots of analogue delay and a little chorus - it makes clean sounds very wide and deep.
Don't expect a screaming gain monster with this pickup, but if you want a very versatile, slightly more vintage sound, this is a great pickup to try.
