Now that I have my stingray 5, I want to turn my cort curbow 6 into more of a smooth jazzy bass. I ordered some TI jazz flats. It came from Mr. Curbow with the US bartolini pickups (not whatever comes with the corts). I was wondering what onboard preamps would compliment this bass. Also, any other pickups fit this bass? Thanks for the info... I am seriously ignorant when it comes to electronics.
