Great strings

By Sweetwater Customer from San Jose
Music Background: Classic rock, blues, country rock, worship

Been using these (& the RS66 on my 4 stringers) for over 40 years. They are on all of my fretted basses. Never even considered using anything else. Nice bright tone & they last. I play several times a week & only need to change them about every 6 months.

The gold standard!

By Graham
Music Background: Bassist

I love Rotosound strings, I play in my high school's jazz band, and I just play bass for fun too, lol. Rotosound strings never let me down, they are durable, they are nice and abrasive, so my fingers don't slip when my hands get sweaty. They are nice and bright and cut through the guitars, drums, and trumpet very nicely. They have that perfect blend of warm, deep low end to lay down the groove, and they have that bright sting and punch on the top to cut through a mix. Love Rotosounds and always will!

Your the best

By Kevin C. from Louisiana
Music Background: Honky tonks bars 1974-1992

I ordered three sets of Rotosound strings. When I opened one of the 5 string sets it was missing the low B string. I called you guys and yall said we'll take care of it. I was expecting to receive a single low B string. Yall hooked me up with a whole new set. Now instead of saving my old strings in case I pop one. I have four new ones. I didn't expect that. Much praise to you guys. Much praise!!

The Best String Available

By Dave B. from Dulzura California
Music Background: Benn playing Bass for 50 years, drums for about 35 (semi-pro)

Haven't installed this set yet but have been using Roto's forever. Nothing compares to the clarity, punch and playability.
Will always use these strings

The real deal

By Dan S. from Myrtle Beach, SC
Music Background: Vocals, bass guitar, and harmonica player and songwriter, performing live and in the studio.

In 50 years of playing bass guitar I've tried other strings from time to time but always come back to Rotosound Swing Bass 66 Stainless Steel Roundwound. Not only do they sound terrific new, they hold up well under the dire humidity here in Myrtle Beach, SC, USA. And, the threaded ends help the stringing process. Highly recommended.

No brainer

By Ken M. from SAN JOSE, CA
Music Background: 30 year professional

I've been using the 4 string set (RS66LD) for over 40 years. When I picked up a 5 string, there was only one logical choice. That bright, punchy tone can't be beat. And they last- I change strings twice a year with playing on them several times every week. They sound great whether I'm playing rock, country, blues or praise music in church.

punch

By Bobby from Tennessee
Music Background: all styles pro player 25 years from studio to tours

Ive used Rotosound over 35 years and they just have a punch no other string ive played has. I use this 5 string set on my Yamaha bb passive and it really can do any style of music. Ive played on pro gigs with artists from rock to country to soul. They just work!

Warm Punchy and Bright

By Rene H. from New Braunfels, TX
Music Background: Professional Rock Musician

I've been playing Rock music for over 35 years, professionally about 30. Round Wound Roto Sound bass strings have always been my companion and best friend, on stage and in the studio. John Entwistle was my hero, knowing he had a say on their production is all I had to know. Hands down the best Rock and Roll bass strings in the market!

Don't take my word for it, get a set and see for yourself!

Plays well, sounds great!

By Frederick R. from Newport News, VA
Music Background: Experienced bassist, acoustic guitarist, and live sound engineer

I just put a set of these strings on my Sterling By Music Man (SBMM) S.U.B. Ray5 bass. They sound great and impressed my sound man who was also a bassist. He was impressed with the jazz sound of these strings when I cranked up the treble.

These strings also are much better to fret than the original Ernie Ball strings that came with the SBMM. The Ernie Balls would buzz a lot, but these Rotosounds would not. So, better sound and better playability means that these strings cannot be beat! Only disadvantage: stings have somewhat a rough texture. To me, the advantages outweigh this disadvantage. I will stick to this brand for my SBMM for now on.
