Strings phosphorus / bronze spun round on a nylon core specifically designed for acoustic bass with piezo.

I just receive them, and they fill me already!
I love their flexibility due to their heart nylon, like their roundness, they are very easy to play and the respondent under the finger.
Their firing low (041-086) does not prevent them from having a good momentum .... must see the length, but I would in a few time to talk about .....
strings quite expensive (37 € in Lord of the string (http://www.lordofthestrings.com/lots/RAPRD/Thomastik-AB344/11001601.html)), but they are worth!
I think I will take up these strings.
