Three of my basses have LaBella black nylon flats. I guess that says alot. My Turner bass has TI acousticores which are full and acoustic sounding rounds. I want that modern sound, especially for slapping. The G string sounds great. But moving to the lower strings, not so much. The E string sounds like a piano string. Very little fundamental fatness. Lots of overtones, like a bunch of tones all at once, thinner, to much treble and zing, kind of hard to describe. I want roundwound sound but with less zing and overtones and more fullness, fatness and body. Any suggestions would be appreciated. Thanks.
