Having taken up the double bass after 30 years of electric I wasn't entirely sure which way I'd eventually go - orchestral playing, slap, jazz, folk etc etc. What I decided I wanted was a string set that would give me a balanced performance across the range of styles so that I could make progress in all options before opting for one style.
I would say the result has been very successful in all the areas I had a right to expect a result. What I mean is that, as I'd rather gathered from readings lots of reviews, these strings give a solid workmanlike performance across a range of genres. Although new to bowing, I'm able to produce full sonorous tones (on the good days!) and when proper players have borrowed the bass or my teacher demonstrates something to me using my bass, I realise the richness that these strings are capable of producing in the right fingers.
The strings are quite forgiving to a new player's hands and I haven't created any callouses or sore spots. That said, they clearly aren't just beginner's strings because, as I say, real players make my bass sound great with them.
The one area I have had less success is in slap. I know they are not "proper" slap strings, but a few videos on the internet show what can be done with them for slap. However, I'm guessing that those players probably didn't learn rockabilly on these strings, even if they subsequently like the sound they produce for a skilled slap player, and I've given up that idea until I either restring the bass with something else entirely or get a dedicated rockabilly bass.
All in all I've felt these strings have worked with me, allowing me to learn to play the instrument and fitting a wide variety of genres. They came properly boxed and packaged and in secure outer packaging. All in all I've been thoroughly pleased and would certainly buy again.
