The parts thing is a great options. I briefly had a tony franklin. They are great basses but really noisy. The J pickup is wound to Tony's specifications and they are really noisy. The P pickup is quiet as quiet can be. If you play in just the P position probably the best fretless p on the market. I just could not take the humming from the J pickup. It is as loud as when you have one jazz pickup all the way up the other off.
