D'Addario Electric Bass Chromes Flat Wound Super Long Scale, .045 - .100, ECB81SLstar rating 4SammyMarch 11, 2010These strings are nice. I am not going to say they are the best flats ever. But for the price they are nice. When you first string them up on your bass they are a little more crisp and brighter then you would expect but as they age they darken tone wise. What I do like about these is they have the different colored ball ends for each gauge and that is useful to me because I like to save strings after I replace them. I'd say these have more of a decent tension, it's not something you have to fight over... OVERALL GOOD STRINGS.
