I have had three sets of strings on my Jazz style bass: LaBella Rounds, LaBella Deep Talkin' Flats, and TI Jazz Flats. I definitely prefer the flats, so I won't go into a discussion of the roundwounds. The LaBella Flats really had a lot of extra noise associated with fretting. You could hear the strings being fretted with a click as the string hit the fret. If you weren't totally accurate with placing your finger directly behind the fret, a horrible rattle was amplified thru the speakers. The problem cleared up with the TI Flats. The lower tension causes a few buzzes here and there, but only if I really dig in. All in all, I am happy with the TI Flats. My thinking is that they aren't terribly punchy strings. I am wondering if any of you tone-meisters have tried other flatwound strings in your tone quest. I am definitely into the old school Memphis and Motown sounds. To this end, I am building a P-style bass equipped with an Aero pickup. I am curious about the Fender 9050 strings and the Pyramid Gold Flats. The two reviews of the Pyramids at BGRA are decidedly negative. Any real world experiences would be appreciated.
