Here it is: I have decided I am not happy with the passivisation of this bass. The lack of punch from the neckthrough and the overall brightness mean that it does not make a good passive PJ fretless. I am going to twist it more. I have a set of Bartolinis (the w model, I think. Not much poke but plently of output. Very clean and clear). I will put them back on and re-install the preamp. I am not going to bother with separate volume controls or a balance pot, but just have a master volume and a three way on/on/on switch that will let me play each pickup individually or both in parallel. I don't think I have ever tried to subtly balance a PJ bass in my life. Guitars do this all the time. Think Tele or Strat. Why don't basses use straight pickup selection rather than balancing more?
