I've used a set of this strings in my Corvette $$ 5 with a Darkglass B7K. I play in two Metal bands, and bought them as a recomendation for Metal and record an album from one of my bands.
After put the strings on the bass, I've played a bit to stretch them, only after one day playing I started recording.
The sound. Well, the sound is just insane, that typical metallic sound of new strings is agressive and ideal for Metal music. When I turned the distortion on, the sound was aggressive and harsh as ever.
After that I've recorded with them for about 5 days, 8 hours a day. During that time I've never been with great concern to clear the string sweat. After that extreme usage they still have that metallic/new sound.
One thing that I find important in strings in general is how long does that new strings sound last? Well this ones last a little more than some other that I've played.
Pros
Agressive sound, if you are into Metal, this is your weapon.
Great new sound durability.
With this strings my bass hardly detune.
Cons
Maybe the price, but they worth every cent.
