To many basses out of the four that I own. All are tight basses, But to close to same tones. One of the main reasons is I love Delano pickups. And all have different preamp, but for one I think I'll just try changing out the pickups and try bartolinis. So I'll be pulling out the Delano P/J set and seeing how the Barts do. Wants good with Bart pickups other than their own preamp. Looking for a good ear grabbing body shaking tone. Might be up for a trade. But let me know about a preamp suggestion with Bartolini pickups other than a bart preamp.
