I tried them for a few minutes yesterday and I don't think they sound like a P90 at all. It's strange how many companies use the term P90 in their advertisements when something doesn't fit the mold of either a single coil or a humbucker. It makes me wonder if they actually have heard one?
The cleancuts are brighter than a normal humbucker and have much better definition than a humbucker or single coil. Lows are tight and punchy, highs are fat, and you can hear every note in a chord with no mud. If you play complex chords and do a lot of arpeggios that's where it really shines. I you play a lot power chords with distortion it probably isn't as good at that or playing leads.
They would be a good pickup for a hollowbody. I'm going to see if I can find a Tele Thinline body to use them in.
