I'm looking to do something different too. I like the Bart system I put in my Brute, and it was definitely an improvement over the stock system, but I'm still missing something. It might just be my imagination....
The other weird thing is, I don't feel that the B string is as solid as I'd like, i.e. like the B on my Cirrus. The tone I get from it is almost compressed-like, characterized by a boomy-ness. It was like this when I bought the bass, so I don't think it's an electronics thing. If I can find a Lakland setup I might try that, or maybe a Nordstrand setup.
I really want to get a neck made for my Brute...All maple, satin black back...I wonder how much that would cost lol?....
