Bought 2 weeks ago here on talkbass for $260AUD. Seller stated: “ Sonores by Genssler metal flatwound gut great versatile warm sounding with clarity Arco or pizzicato in good used condition just had light use on one bass. Can’t remember the model name“ My first impression of these strings was “woah these are awesome”. But after having them on for a week decided I had to go back to plain gut. In my opinion these strings are a bit thicker, a bit softer in tension, and a bit more gut-like in sound than an Oliv. I’m guessing they are Genssler’s Basso type string but I have no clue really. String condition is exactly as I received them, and will sell them a bit cheaper - $230 including postage.
