I've had these a couple of weeks now. I have a light carved bass with a low action. These strings give a nice woody sound without buzzing. They still have quite a low tension, giving little sustain or attack but are good for duo/trio acoustic jazz/bossas without drums. They need plenty of EQ manipulation if amplified. The big negative is the performance of the E string, which appears to be the same diameter as the A string and is poor. I see that the makers now recommend buying an additional 'Twister' E string, but if it is any better, it should be included in the set.
