I've got a set of Fender Cobalt semarium Noisless pickups, I also have Fralins, and David Gilmour pups, all are excellent, But the more I play the fender noiseless, the more I like em.
They have a great range of sound and performance, they can sound crystal clear bell like tone, and they can turn dirty crunchy as well. All dependant of the amp settings of course.
But the fralins for example dont sound as thick and gritty when the amp is pushed hard on the dirty channel.
I don't think they get their due reviews because they are not a boutique pickup. BTW the fender noiseless are in fact humbuckers, stacked.
