I love these strings. It's true I often say that after putting on new strings, but these strings could be keepers. It took about two weeks for them to come up to tension, but as they did they just kept sounding better and better. The E was a little floppy at first but now it's no problem.
You notice how in different string threads people often remark that the particular string they are talking about is loud? Spiros are loud, Evahs are loud, Jazzers are loud, D'Addario Pizzicatos are loud, Dominants have a loud fundamental. Well, the Blues really are loud, AND with less tension. I don't think it defies the laws of physics: the ample vibration from the strings shakes the hell out of the bass, causing it to resonate in a way which creates a lot of volume.
They are bright and have great sustain, but in a way that sounds different from steel core strings. Overall the strings sound a little nasal to me, but not in a bad way --it's high midrange, what I used to call "honk" when I played the bass guitar. Since they are not too bottom-heavy, they amplify easily --unlike my experience with Evahs-- in addition to having a very pleasing acoutic sound.
And the low tension is saving me on my long, loud weekly gigs.
General question: What's the difference betweeen Animas and Compas 360s?
