Ok, first of all......all the reviews that you've read on here about the Single Coil pups are TRUE!!! They are the most wonderful pickup and just tear through the mix with authority!
I installed these in my Standard 5 (Ash/Maple) and played thru my Markbass F1/Epifani UL2-410 rig. The F1 was set flat with the VPF around the 9:00 position. Man of man was the tone absolutely killer. The mid focus is just cutting while the low end fattens it all up. Boosting the treble on the bass gives you all the sparkle you need up top. With the bass set at full blend and no boosting of the bass or treble the tone is just stunning. That mid focus is perfect for finger style playing. The bass seems to be more clearer as well. I could not hear any 60 cycle hum from these pickups at all. These pickups are a tad louder than the HC pups too. I needed to adjust the input volume on my F1 because they were clipping a bit.
The venue was a large 5000 people capacity function hall. 2 stages with large PA, Lights, etc. There were over 40 bands playing. We went on around 4:45. Close to 500 people were there at that time. I had the volume up around the 11:00 position on the F1 and it sounded awesome.
Overall, I consider the Single Coil pups an upgrade to the already wonderful HC pups found standard in the Sadowskys.
YRMV....but I doubt it.
