For a point of reference, I use them in a P&W band and we play the modern stuff with a full band. We all go direct and use in-ear monitors. I use a Tech 21 Para Driver as my DI with a little compression.
Simply put, these strings are perfect for what I do. They make the band sound bigger. My bass tone retains enough of the top end with these strings, but it has a much bigger fundamental tone to it than if did with any of the round wounds I ever used. I can dig into them with a pick and make them rock or play them finger style and mellow them right out. I'm never switching.
A lot of players using flats like them totally dead, I prefer them with their newer sound, so I change them about every six months to get my sound, still WAY less than I had to with rounds.
These are smooth, and every string is bright with some to spare. I might even put these on my fretted bass!
