Rotosound RS66LD Swing Bass

I have used Rotosound steel strings on and off for years and you consistently receive a product with the same pro's and con's.

Pros:
-Bright 'zingy' sound
-Deep, solid low end
-Rough feel (might not be for everyone but I prefer it)
-Nice covered string ends (stops the machine heads from getting scratched)

Cons:
-The tone 'dies' rather quickly, especially if you sweat on stage
-When the tone 'dies' you are left with a clunky, unpleasant tone
-For me the A string seems too light gauge and the D too heavy

To summarise, I absolutely love the bright tone of these strings, but that tone just doesn't last long enough, leading me to look to other brands. Other brands may not be as bright as Rotosounds, but the tone they give you seems to last a lot longer, and can still be pleasing when 'dead'.

I use these on my Fender Jazz. They have the brightness I like and bring out the natural growl of the bass. Perhaps the only drawback is that they are not the longest lasting string around. If you play often and hard they will need to be replaced within a month or less. This, of course isn't the end of the world considering the price is very competitive. DR Highbeams are similar, for example, but will generally cost a good deal more. Occasionally there can be some quality control issues. I have bought packs where the E string sounds a bit dead. Then again that might have to do with an error in my stringing the bass.

This where my first Rotosound strings i played, and i have to say, i like the sound.

Rotosound where the company which introduced the Roundwound Stringtype,
(everybody bevore played Flatwound)

I was looking for new Roundwound, because i dont like the Daddario ones,
and a friend of mine meand this Strings would be great.

I have to say, the sound is good, fits very good with a Precision Bass,
and i could use them for 3 Month.

Then the Sound loose a bit of his "crunch"

A friend of mine had a Problem with the E String, it was dead.
i heard from others that this problem could be, but this happend sometimes even with Erny Ball.

I found it great that Rotosoud use organic material for the Package,
so you dont have so much garbage.

First thing to notice about these strings is they changed the packaging quite much. It used to be a sheet for each string. But now, they're touching each other. Felt some lack of quality there.

Nevertheless, sounding is superb!! I've put them to my '73 jazz bass and thing is singing! I'm having a blast each time I play stuff with slapping.

All the other people had written that these strings don't last long in terms of tone. Whether or not, they're cheap and giving so tasty sounding. I'd prefer to buy 5 or 10 packs of Roto instead of Elixir.

Those strings are not very even and many say they harm your fingers a bit as they are hard to play because of its rough surface. Well it is kinda true on the one hand, on the other hand those strings are not too hard to pull and they are great to play. Those strings are historical, developed with the help of John Entwistle and played by Prog Rock Giants like Chris Squire and Geddy Lee.
Strung onto the bass being new and fresh they do not have much bass and are very unique and perfect for Rickenbackers and Jazz Basses. Those strings tend to lose their highs very quickly and then sound very different. So everyone should decise onself if you like them or not.
