Hello everybody, My second post, the other one asking to ID my Samick bass. I get huge noise from my pickups when plugged into my recently repaired Ampeg V4 amp. I have done a bit of reading and it seems I need to: 1. shield the pickup cavities etc with copper tape to prevent radio waves from the Ampeg V4 transformer getting to the pickups. 2. Upgrade to the best pickups for my bass and sound that will minimise noise. I have read a few threads recommending different pickups. Correct me if I'm wrong, but it seems I need noise cancelling passive precision pickups that would be good for the old soul/reggae soft sound. (many say it is more to do with flat wounds, playing up the neck and not plucking too strongly, which I agree with, but I have no experience with comparing pickups. I should go watch some youtube comparisons maybe). And a noise cancelling jazz bridge pickup. 3. Make sure the pickups or shielding is grounded. Anything else? What would be the most NASA solution to minimise my pickup noise. I want to get the amp made quieter as well. But the pickup noise is extreme. I read passive pickups have the vintage fat sound that I am after. Active pickups would be the quietest I have read. Audere sell a preamp that claims to keep the Fender Jazz passive tone using an additional noise pickup that doesn't pickup the strings. Probably not relevant to my situation. Do all pickups fit the same dimensions? I have included a photo of the offending rig. My idea is to get the recommendations of you more knowledgeable bass guitar people on what are the quietest passive pickups for my PJ Samick that will possibly be appropriate for the vintage groove sounds of soul, reggae. I did read one thread on TB asking about pickups for reggae, and someone suggested any good pickup will do, just get flat wounds and play close to the neck etc. Maybe different pickups aren't as important as how you play, strings and tone control/pickup settings. What would give me the quietest bass with that soft round tone I've described. Would higher output pickups be best? Are some pickups better at cancelling noise than others? From the handful of threads on passive noise cancelling pickup recommendations, I read one person claim Bill Lawrence's Wilde pickups are the quietest passive pickups available. Are they going to be good for the tone I like? I suspect if I had a new Fender Rumble 500 210 combo it would create much less radio waves than this Ampeg V4. I want to make the electronics in this bass guitar as good as humanly possible for low noise vintage groove tone. I want to get the recommendations, order the pickups, get my tech to replace the sockets and everything, shield everywhere with copper tape, ground everything, get my amp tech to quieten the V4 if possible. Have I missed any details? Thanks for any assistance from you more experienced people. Roman.
