Pirastro Perpetual Bass 3/4

These strings have an amazing pizz sound. The tension is a little lower than spiro weichs but makes pizz playing really kind to the right hand. Also the strings are really well make. A lovely flexible string which is bright under the bow but none of the scratch of spiros. They are the best 'hybrid' string i have ever played. They are supposed to be a pizz string and sound awesome with a punchy fundamental and a loud and long sustain . Bright but not too bright. They move effortlessly under the bow also. i love love love these strings. i have been a bit spiro weich user but these strings are much better for me who plays a lot of jazz pizz and some orchestral stuff too. Highly recommend these strings. The only thing now i need to learn is how long they last? The steel rope core hopefully will last longer than a year or 2?
