I bought this string by chance - not expecting a high level quality due to the pricing of the product. However, this string set surprised med massively. The strings have a great clarity and definition to the tone and had great presence and round bottom with a solid bass tone. I used this string set on an old Vintage 4-string, and they served it right having a long durability if you play 6 - 8 hours a week, they can last up to 2 moths before the dull up the sound for real. I think that considering the price and the manufacturer, I say thee strings are a bargain.
Only critique I have is that Fender could have made the G-string a bit longer, so I could wind the string 4 times around the tuning device. But hey, I got 3 rounds without cutting the string end. So - if I want to save money and buy new strings and switch them often, I would go for these bass strings.
