Product Description

Product Description

Highly praised by Bass Player Magazine as their favourite flatwound string. Unique materials produce a unique tone.

From the Manufacturer

The flatwound bass string that’s been awarded many accolades since its inception in 1966. Wound with the premium alloy Monel, Jazz Bass strings sound deeper and offer more resistance than the more commonly used stainless steel wrap.

From the manufacturer

SM77

Rotosound SM77 Hybrid Gauge Stainless Steel Monel Flat Wound Bass Strings

The Monel flatwound bass string that’s been awarded many accolades since its inception

Why do so many artists choose Rotosound?

By helping music icons like Jimi Hendrix, John Entwistle and Geddy Lee to create their amazing sounds, Rotosound strings have become synonymous with the British Tone. Renowned throughout the world, Rotosound is the home of legendary products such as Swing Bass 66 and Roto strings.

For over fifty years now their strings have changed the sound of rock and have been used on some of the most amazing albums recorded by some of the best artists in the business.

Founded in 1958 by James How as a small, UK based, family-owned and operated company, Rotosound core values are little changed today. Each string is physically and visually inspected at every stage of the manufacturing process to get maximum consistency, ensuring each one is unrivaled in tone, tuning stability and durability.

Why the SM77?

The Jazz bass series has found favour with so many of the world's leading artists including the likes of Oasis, Steve Harris, Roger Waters and Herbie Flowers.

The Monel 400 tape used in the strings making brings out the true character of these strings over the competition who are happy to use the much less costly flattened stainless steel.

An iconic, legendary British brand

  • Manufactured the "old fashioned way" by hand on machines built at the end of the 1960’s
  • Used by many top leading artists including Oasis, Steve Harris, Roger Waters and Herbie Flowers
  • Long Scale

Customers are mixed about the brightness of the strings. Some mention that they sound like Round Wounds, very bright for flats, and a really nice light gauge for harmonics. However, others say that the tone is not as bright as roundwounds but not as muddy as some flats.

5.0 out of 5 stars Nice strings, but not exactly what I was looking for.
Reviewed in the United States on January 28, 2014
Style: SingleVerified Purchase
I ordered a set of these for a P-bass because I wanted the semi-dead sound of flat wounds. Unfortunately for me, they were actually brighter than the round wounds I had on there. Despite this I am really enjoying these.

Bottom line: If you like flats but still want a somewhat crisp high end, these are great.

Update:
It has been 5 years and I still have the same original set on the bass. It doesn't get used as much as my other basses, but I do play it frequently so they have worn in. The strings are still very bright compared to other flatwounds I have played. I have grown to love the sound and I am glad they weren't dull out of the pack like I thought I wanted. When they have been too bright, I just roll down the tone and get the subby dullness. But the great thing about these strings is that I can turn the tone back up and enjoy the brightness. Couldn't do that with most other flatwounds I have tried.

I've gotten so I won't use any other string on my P bass and JAZZ bass. I dont change my flatwounds often but love the mo-town sound of these strings. Still able to replicate a Jaco sound by using only the bridge pick up with treble up and bass cut. Well balanced across the fretboard with my P bass and Jazz base. I havent used them with my acfive Spector bass but will soon. My music store doesnt stock these so I rely on Amazon. Never been disappointed.

Hands down best bass strings for a fretless. My fender w/ nordstrand pickups loves these strings. Plus, you don't get the same calluses you would with round wounds, and they're a really nice light gauge for harmonics.

3.0 out of 5 stars bad string
Reviewed in the United States on January 24, 2012
Style: SingleVerified Purchase
I received the Rotosound 77 jazz bass strings. Got them in a timely matter no trouble there. The problem is that the "D" string is dead. A thuddy sound instead of nice clear tone. I use these strings a lot and this is the first time anything like this has happened. What now?? I feel cheated because the string is not right. It is the .60 string on the 40-60-80-100 set of flat-wound Rotosound SM77 Monel Flatwound Hybrid Bass Guitar Strings (40 60 80 100) . I guess I will just use it, practice only for now, then after some time when needed, put the other set on and see what happens there. I bought 2 sets of course. Hmmm, disappointed.
7/24/15 got another set and same thing, except this time it is the E that is dead. I guess I will have to give up on Roto, my all time favorite strings. :( Too bad. That is three sets in a row, different sting each time.

This is the first time I have used RotoSound flat wounds and they are amazing. I put them on a 1964 P-Bass and play through a MarkBass 2/10 combo amp. Great depth and articulation if needed.

5.0 out of 5 stars Nice flat wounds
Reviewed in the United Kingdom on March 16, 2022
Style: SingleVerified Purchase
I'd previously bought some rotosound nickel round wounds for my new fretted squire vintage jazz bass, but I decided to try flats instead because I think I just hate round wounds. I've got fender flats on my fretless but I thought I'd give these a go. Overall I'm happy with them, they have a nice tone etc, not as smooth nor thumping as the fenders, however the fretless would have an impact on that, and the silks aren't as tidy either, I've found i enjoy playing them way more than the round wounds which just felt cheap to me. I suppose they have a tone more similar to round wounds than to your classic upright bass, very little finger noise, overall I'm happy with the purchase but would probably spend a little more next time.

Edit: I've had these on the bass for a month or so now and feel a little bad about my original review.
These are really good and bumped up to five stars.

5.0 out of 5 stars Rapporto qualità-prezzo eccellente
Reviewed in Italy on October 21, 2021
Style: SingleVerified Purchase
Ho acquistato questa muta last-minute, avendola scovata all'incredibile prezzo di 28 € circa; alla luce di ciò, ho subito scartato le Thomastik Infeld che stavo per comperare.
Che dire: la grande qualità che Rotosound garantisce da settant'anni e a cui sono stato abituato dalle storiche RS66, prezzo incredibilmente basso (per essere delle flatwound) e timbro alla Roger Waters. Le ho montate sul mio Precision Bass del '68 e credo che non le smonterò mai più.
Nota importante: sono molto rigide, con una tensione che definirei "alta" – ma non quanto le Jamerson – e un feel sotto le dita che strizza l'occhio alle half-round: l'opposto delle Labella o delle TI, insomma.

These flatwounds are a treat on my fretless bass. Slide like a dream compared to the roundwounds that came with this bass. Tension is higher - need to push harder to bend notes, but minimises buzz when tuning down a string (BEAD, as opposed to EADG). Recommended.
