Well I tried these on a different bass today and they sounded really, really good. It was a Regenerate Heritage Plus (pic included because it's hard to describe), and man it sounded good. They sounded good in every PU setting. Thus far about every string I've put on it does, but these likely are the best. These strings sound very similar to the GHS Pressure wounds that were on it and were my favorites thus far. After today, the Cobalts are staying on. I think I'll try to snag another used set and try them on something else.
