I strung my bass up in the evening with these strings tuned it up, and let the bass sit over night. The following morning I checked the tuning again and began playing. The strings proceeded to stay in tune and have a big full sound. Lots of clarity and fullness and so far, I have no complaints. Great price too. I bought a four string set with similar results. Looking forward to the future Sheptone tshirts. Thanks Guys!
