These are some really really good strings, for your 5 string bass. they don't just look really cool, they feel amazing. and the tone from them are fantastic. I have found just one problem with them. On my active 5 string bass i have noiseless pick ups, which with these strings can be a problem. As soon as i put them on, my pick ups started buzzing and i found out that it was because of the strings. But otherwise i found these strings fantastic and i salute them highly and recommend them warmly. If you want some cool black bass strings, that sound fantastic, these are the strings for you. Thanks DR!
