I see nobody has written a review on this one. Is it possibly because there are so many newer stacked singles in the line that have more output? Maybe.
This is my experience with it. The output is VERY low. The tone is absolutely gorgeous. especially in the neck position. They are just a tad warmer, but still have a pretty nice single coil tone along with being dead quiet. Just don't expect screaming output. You will have to adjust them closer than your standard single coils, or adjust gain/volume accordingly. Or use a boost pedal, overdrive like Mr. Malmsteen, or simply adjust your distortion settings a little higher. I actually used to use this pickup with traditional style humbuckers with good results. The big trick was to not go too high output with your bridge humbuckers, adjust the hs higher, and badda boom badda bing.
It is a VERY good pickup, just a little misunderstood because of its main user. Yes he flat out screamed, but his pickups were a little weak, boosted by the od250, and into a CRANKED 50 watt Marshall.
The only thing that confused me was the super high D.C. resistance, but low output. Most pickups with a dc resistance in the 20+ range are LOUD. Anyhow, maybe someone who is more well versed in pickup winding will chime in on that one.
