Using these strings on 5 string J.Rubner bass. These 4 sound beautiful and the thing is that you can find great double basses with a strings like that in every concervatory, academy of music, because It's the cheapest and best strings for a price like that.
In opinion playing pizzicato with these strings is great, the quality of the sound is professional, but I would rather play with more tensioned strings, because these are a little bit low tension. There is a good point of it - you can keep the strings further because it's very easy to press them, even when you play thumb positions.
Playing with a bow is perfect option in orchestras with these strings, because these get strong and specific sound.
So this is a perfect choice for everybody. I just recommend this for everyone - from begginers to professionals.
