So today I put some Rotosound SM55 (.40 .60 .80 .100) strings on my bass. These are the first pressurewound strings I've ever tried. These strings are SO AWESOME so far. I haven't broken them in yet. They are very bright and rich, kind of piano-like. The mids are strong and really sing. The lows are good and full. They sound A LOT like the Rotosound 66s that I tried a long time ago, maybe even better!. They have a sticky feel that reminds of the 66s. I'll probably get to used to it if I keep playing them. They are also very smooth, maybe even smoother than DR steel Lo Riders (been a while since I've played those though). These strings replaced EB Cobalts (.45 .65 .85 .105). I prefer the smaller size of the Rotos. In terms of sound, the Rotos are nice and loud, and not as harsh as the Cobalts. I really can't wait to see how these awesome strings age!
