Rotosound SM66 Swing Bass

Good strings. They have a high amount of treble when brand new, but within a couple of weeks they settle in to a smoother, but still aggressive, sound. I generally keep them on for 3-4 months. Used on a Lakland Darryl Jones signature Jazz bass (article number 386089).
They?re the strings Entwistle used, so either you like them or you don?t, but they are the original roundwound strings so definitely worth buying once to try out.
Nice brightness, good presence, good even response across the strings (although in some sets, I?ve found the G string can be noticeably stronger than the D or A).
Once bedded in, they have a nice flex to them and are easy to bend. They maintain their tuning very well too - nice and stable.
They do need a bit of playing to settle in though, both tonally and in terms of pitch - hence the four stars. Other roundwounds that sound bedded in straight out of the packet (elixer springs to mind) are noticably more expensive though.

The standard string against which all other roundwounds are compared. Would recommend.
