I'm not what you would call a "Bass Player", I don't know that much about Bass gear etc, but I do regularly use a Squier Jaguar Bass for recording with (I am usually a guitarist or singer rather than Bass).
I was trying to achieve a particular sound for my bass, pronounced mids and a nicely defined top-end. That's the best way I can describe it, Bass players might call it differently, but I was after a kind of Justin Chancellor / Les Claypool direction.
A Bass Player friend of mine recommended I try these Hi Beams and the Ernie Ball Slinky set (blue packaging), and after trying both sets out, I found the EB's much more to my liking.
That's not to say these DR's weren't good, they were great! I put these on the Bass first and the difference from the last, thicker strings was great. I almost settled for these but curiosity got the better of me and I tried the EB's out and they were just that bit more to my liking.
These strings are definitely for anyone who wants a clear, bell-like tone, they reminded me a bit of a Piano, if that makes any sense? But my personal opinion is the Ernie Balls were slightly clearer with a more defined high-end response.
