I like to change my strings constantly instead of buying an expensive set every six months so I bougth a lot of Strinbergs the last few years without problems, they tune up and had a decent even sound at least in the begining. The last set I bougth was a disaster, no tunning and the E string was dull, like was used for years. Defective ones. I sent Strinberg a message but had no answer. Has anyone had similar problems?
