Hello, I have an Ibanez SR645. The electronics are setup like this: ::Neck Pickup IBZ DX5 Passive ::Bridge Pickup IBZ DX5 Passive ::Active EQ EQBII 2-Band I am currently playing through a new Peavey TNT115. I love the bass itself, but am now looking at ways to improve my sound. I find that when I play with fingers, the sound is too soft, and I'd like to get a deeper but sort of hollow sound. Also, I find that the B doesn't sound as good as the other strings. I'm looking at the following options: Replacing the DX5s with either Bartolini 72M45C pickups or EMG40HZ pickups. I am pretty good with a soldering iron and can read basic schematic diagrams. I also thought about picking up a sansamp RBI instead. Which of the two will improve my sound more? Any other suggestions?
