its strange ive got a lot of lace sensors and they all seem to have that classic single coil sound, ive heard people call them sterile and overrated but ive also seen a lot of people using them (amatures and pro's) pete townshend and clapton to name 2, i think clapton used lace pickups (a set of 3 gold sensors) to perform layla live many times thru the 80's and 90's and i think i remember him using them on a guitar at that recent (last couple of years) cream concert at the royal albert hall.
that said ive also seen him use the fender vintage noiseless pickups (which i dont know anything about) i havent tried them so couldnt say if they were any good, but the same tones (old songs dont seem to change much live even though the hardware does) seem to be achievable with both types of pickup.
maybe it comes down to effects, theres a few songs (shes waiting/white room) on the live aid concert (disk 3) that seem to be flooded with effects (chorus/wah) maybe thats where the 'sound' comes from....
