La Bella Acoustic Bass Professional Series Chrome Steel Flat Wound Rope Core Solo Tuningstar rating 5Helmer HemnesNovember 12, 2009This is the greatest sounding doublebass strings i´ve ever had. They have low tension and sounds great in studio and amplified. The sustain is incredible for a jazzer. The strings is great for the virtouso player. Thank you for making me want to play all the time. Love from Helmer jazzplayer
