Tried them, was unimpressed. The ones that are supposed to sound like humbuckers are....just ok. The ones that are supposed to sound like P90s or single coils, well, same issue I have with a lot of his noiseless single coils. The frequency response seems to drop like a stone past a certain point, and while on first impression they sound ok, that lack of "air" frequencies makes the pick attack kind of off, and ends up killing the feel of the thing.
Same thing with his noiseless P90s. They sound great at first, but they suffer again from that lack of extended frequency response, and eventually the stiff feel they imparted made me ditch them. They do sound rather like P90s, but just not right on the extended highs. I ended up putting a DLXplus set in that guitar, with the screws removed from one of the coils on the neck pickup. Even though much darker than the Kinmans and certainly not traditional P90 sounding, they "played easier". Even with the screws pulled from one coil that DLX plus neck is dark, but it didn't suffer from the extended high end drop off the much "brighter" kinman does, and so it doesn't make the pick attack stiff.
