I've had 2, a Fender Custom Shop, and a regular Phil Kubicki.
Of the 2, the Fender Custom shop had the better electronics (sorry TPJ) and was tidier inside.
The drop D is an awesome idea, meaning the notes on the fretboard stay the same (unlike with a hipshot) plus you still get the E and Eb. Trouble is, the spring in the mechanism that frets at the nut, tends to lose some of its tension over the years resulting in a nasty fretbuzz type sound, even when playing other notes on the same string.
Only single balled strings are needed, which is good, but trying to re-string is a pain, as some kind of ratchet (that I never had) is needed to tighten the bridge, so the fine tuners can do their thing.
All the sounds are there, passive and active, various filters cutting and boosting, and coil tap options. And if you like the jazz type neck (like me) the playability is fantastic and well balanced, if a little heavy.
I found recording worked best from passive, live full on active. Hope this helps.
