I did this a year or two ago and it's that time again. I have a 4-string set of DR Red Devil's tuned BEAD (.065, .085, .105, .125). They have been on my bass for a year but have only been played maybe 10-20 hours total, the rest of the time the bass has been in it's case. I also have a BEAD set of Ernie Ball Power Slinky's (.070, .085, .105, .135).. These are also a year old but only have maybe 10-15 hours of play on them. Both sets were never gigged and only played in my house so there isn't any sweat or "grime" on them. I've been trying different brands of strings to get one of my basses sounding the way I want and both of these sets were just used for testing purposes and I just don't have a use for these anymore. I'm just asking for a few dollars to offset shipping costs, but otherwise they're yours for the taking!
