Hi, I am looking to replace the tuning machines on my 04 Fender Precision Bass and am having trouble finding a direct match to the pattern. It's a double guide post design with the posts below the shaft. I believe theyes changed the design around 08 or so. Either way I am looking for a set of quality machines in black to replace mine. Does anyone know what would fit with the least amount of modifications to my headstock (preferably none). Thanks so much in advance
