Depends on gigs and studio and stuff and the bass and setup. . Pretty much any time we play a show where I feel the PA is good enough to justify it. In the studio I've actually used two sets in one day before. But i won't change strings for practice if we're taking a break between shows to write and stuff. I'd say on average I change my strings about once every 6 weeks. I will also add that washing your hands really well helps strings stay brighter longer. If you're not wanting to buy strings as often I'd try flat wounds and see if they work for your band. A lot of people that play flats rarely ever change their strings.Hi guys, was just wondering how often do you change you're strings? Mine are five or ten years old. And lately, I'm not liking the sound I'm getting out of my rig, witch is a hartke HA7000 with a 15" and a 2x10" with a tweeter. Now, for many years I loved it. But lately, I don't know if its my ears, or maybe the amp. But it just doesn't sound like I want it to lately. The guys in my band are telling me its my old strings, but I don't think old strings sound bad, they're just not bright. Was just wondering how often other bassists change they're strings.
