Hey I want my passive PJ Yamaha BB-x to have that little extra..." ". you know.. i'm happy with it, but everynow and then i need it to go to "11". My first thought was the installing active preamp. Bartolini or aguilar? Can you give me information on the compatibility of these preamps with my bass? And how they sound different? My other thought was just to do the EMGs. I'm afraid that the EMGs will cause my sound to be to "popular", when what I want is to add some shaping ability to my current tone. How will these EMGs compare? Thanks!
