I didn't actually purchase this pickup through Amazon but I have an Ibanez QS320 that it came with.  The previous owner of the guitar actually put it in although he got the wiring wrong and I had to fix that.  My all time favorite pickup is the good ol' DP100 Super Distortion and I never put much into blade pole pickups.  All that changed, however, when I plugged this guitar in.  Very nice highs and sustains very well.  I can get harmonics from most places on any of the strings.  The bottom end is fine, the DP100 has a better response in the lower frequencies I think.  Some say this pickup is only suited for high volume output but of all the guitars I have ever had, many with single coils, this thing can beat them all when properly wired with the selector in the next to bottom selection.  Shimmering clean tones and acoustic like sounds can be had from this thing so it is versatile.  If you want to scream leads and then clean it up this pickup will do that for sure.  Totally recommend this as a player of guitars for over 30 years.
