Dear tb, I am searching for a preamp for my P/MM bass. The most important features are: The bass should sound like a stingray with the humbucker soloed AND the preamp solves the problem of the different impedances. The pickups are an SPB-3 and an SMBA-4. I am currently using a Noll preamp with a Mixpot, but it doesn't quite cut it in both the sound and blend departments. Thanks for the effort!
