These strings were something that I wanted to test out. They turned out to be some of the best sounding strings I've had to date. They just have the perfect tension. They can last anywhere from a month or two months with regular practice and playing. The bite you can get from them is better than other strings I've used on my guitars. The price is definitely worth the sound they can make. I first used them on my 2018 Gibson SG Standard, and it sounded just right. They are just the strings to always go with in my opinion.
