Just ordered a set of Sadowsky Flatwounds... I'm hoping those to be the best ever
I've used Labellas Deep Talking Flats, and Daddario Chromes, and TI's to this date.
Labellas (On P Bass) - Still My Favorites, but looking for a little more aggressive tone while retaining the flatwound-ness... Also, the tension is OK, but a little less would be nicer for me I think. A little too scooped on my E strings (Using SD Antiquity II, which isn't helping... was too deep and non-defined at times on the E string)
Chromes (On P Bass) - Nice tone, not as "phat" as the Labellas, and more agressive when digging in. Tension is better, but still not my ideal at this point, but only tried them for a short time and my bass wasn't quite setup to my liking. Very "Ringy" strings on Harmonics and when just letting strings ring out was more than I was used to with the Labellas. Nice ringing I guess, made me laugh, but almost seemed too much. I will give these a try again however with a brand new set (tried an old used set) if I don't like the Sadowsky.
TI (On J Basses) - I have them on a fretless right now, but have also tried them on variuos J basses. Sounded great in the mix, but I just don't care for the feel on the, and still not used to the tone. They seem to be breaking-in nicely on my fretless however... I'll most likely keep them there for a long time, as I don't really use the fretless during gigs. I don't plan on using these again on a fretted because the tension is just doesn't work for my playing style.
I hope that helps.
