I keep getting a clicking sound from my pups and i dont like lowering them. SO it means that i need to cover the pole pieces. Ive tried covering them with tape. for certain pieces i need 2 layers of tape. this is ordinary sellotape(whatever your call it), its the clear stuff. Ive done a search and people have said to use "electrical tape". what is electrical tape? is it ok to use normal clear tape. and can you get pickup covers that dont show pole pieces? I mean the black covers. not actual pickups.
