About a month or 8 ago I put Pirastro Pizzicato gut core strings on my double bass. These are nice strings, easy to play, I like the sound etc etc but strange enough, the strings keep breaking ... even when I'm not playing, I mean they somehow just tear apart. G-string was broken already twice, D-string once. The local bass shop owner doesn't have a clue about what could be happening, but they don't make any problems and give me new strings. However, now I feel somehow fed up with it & I am thinking of replacing them by Rotosounds. (I play slap and pizz.) Any comments .... ? tx Mr M Antwerp, Belgium.
