Item Description



LONG SCALE 810mm 860mm | 32" 34"

The 'Monel '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.

The RS77 Jazz Bass set has found favour with so many of the worlds top leading artists including the likes of Oasis, Steve Harris, Roger Waters and Herbie Flowers.

The build spec remains a close kept secret but 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.

These strings are still manufactured the "old fashioned way" by hand on machines that James How built at the end of the 1960's.

Flatwound. Monel. One of the original Rotosound sets from the early 1960s. These strings can be heard on many famous albums, used over the years by Sting, Phil Lynott, Steve Harris, and John Deacon. Rotosound makes the world's most famous and highest-quality electric bass strings. Outstanding brilliance and superb tone. Long scale.

Rotosound RS77LD Long Scale Monel Flatwound Jazz Bass Strings

Great feel and sound. Best bass strings ever

Phat tone

These strings feel a little higher in tension than whatever the last set of strings were on my custom P/J (105s for sure). Anyway, they do have a big midrange sound that does need a little tailoring on my rig. My bass is bright and powerful to begin with. These strings have a big bottom and pop pretty good for flatties. They are versatile for handling blues, ballads, rock and have some funk in their cores too!
  • Broad midrange of tone, powerful, can take a spanking

Good tone but relatively lower output

These strings sounds good on my Gretsch long scale hollow body but I found that they produce noticeably less output volume, compared to the original strings the bass came with, and it seems to be due to the monel alloy, so this is what I've read. For this reason I don't think I will replace with the same set when changing the strings on this bass but I keep them on until then.
  • Good sound and great feel.
  • Lower output volume than other stings

I tried these strings, but in the 40-60-80-100 gauge. They are great flatwounds, have a soft and amazing feel. The tension is ok, not very tough.

The tone is not the typical flatwound tone, it has much more midrange. It's not muddy at all. It cuts through the mix quite well, being flatwound.

They are the perfect strings if you wanna try flatwounds but keeping some of the roundwound tone.
  • Nice tone
  • Great feel on your fingers
  • They're not exactly what you expect from a flatwound
