Why do people think that Sire are milking the name.? So Marcus had a deal with Sire, to design a jazz bass, then Marcus thought, oh f*** it, I can't be bothered to give my input to design a P bass with my name on it. I doubt it.
Any one who has an issue with his name on the headstock should get over themselves. The only person who cares about it, is the player. Its just an instrument at the end of the day, make it your own.
