These pickups do what they're supposed to do. They're quite, the silver sounds like a faster strat pickup, the blue sounds like a vintage Humbuckey and the red is fat and aggressive. That said, I personally wanted another Silver in my guitar and the blue in the bridge position, but that is not the problem with the product, just my personal preference. No stars lost there. My partscaster in which they are installed sounds like a total pro level instrument with these.
If you want what it says they do, but them.
Glad they're seeing a bit of a revival lately.
