Ernie Ball Flatwound 2818

These are marketed as middle ground between rounds and flats, and it is about right. The sound is pretty agressive, with lots of attack of rounds. Unfortunately, the feel is also halfway between, becouse these are nowhere as smooth as D'addario chromes on my other bass (both EB3). They feel quite sticky - but I will leave them the benefit of a doubt, becouse they might smooth out in time (or I'll lube them with FAst fret). All in all, I'm satisfied, I now have 2 same model basses, both with flats, but both sound completely different.
If you like a bit more agressive sound but don't like rounds, these are for you.
