Honestly I didn't get to spend all that much time with them since the turnover was getting very rapid at that point during the end of the clip sessions (as I recall it was just a few Tele and P90 sets to go, so we were leapfrogging - I'd be recording a Tele clip while Tim hooked up a P90 set into the LP Jr we used, then we'd swap guitars are repeat the process over), and it's been a while since then so the clips are probably a better representation than my memory at this point!
That said, I recall them being absolutely classic sounding P90s, with a smooth and open voicing no doubt in part due to the AII magnet. As for suitability in a strat style guitar, to be honest I wouldn't want to say having had no experience of that setup. Best person to ask is Tim via email or if possible by phone for the best recommendation.
