I have an Ibanez BTB510E which has the same USA made Bartolini pickups and NTMB like preamp that is in their Prestige BTB line. The sound is thick and growly, thick in the mids. It's a good sound but not the sound I'm really looking for. I prefer a smooth deep sound like a Jazz bass, but I really like this bass in everything but sound. I'm thinking about replacing the preamp with an Audere Classic 4-Band and Norstrand Big Splits. Would this give me a Jazz Bass type sound or would it still be thick and growly or smooth and deep? Thanks!
