Hi, I have read the threads comparing Jazz Bass pickups but I didn't find the specific answers I was looking for, so maybe someone could help. I have a Fender Custom Classic Jazz bass which came with Custom Noiseless pickups. I have read reviews for 'Noiseless Pickups' and also 'Samrium Cobalt Noiseless Pickups'. What is the difference between these.. and are the Noiseless different from Custom Noiseless? I kinda presume that on a Custom Shop bass, the pickups are going to be about as good as they can be, so would there we any other brands that might give me a different sound, but match the Noiseless in terms of quality? Thanks.
