I have a Telecaster custom with 2 humbuckers that looks & sounds lovely that I can't stop playing... But, I do like to play a bit of funk & my humbuckers are a tad ringeee! I took it apart to maybe coiltap but looking at the hum it only has 2 wires not 4??.. Plus the hum's looks like they are filled with wax???? Do I need to buy new humbucker or can these still be coiltapped? Plus is there any other way to make a humbucker sound cleaner?
