Description

Immerse yourself in the world of vintage tones with the Rotosound RS77LD Monel Flatwound Bass Strings (45-105). These strings have been meticulously crafted for over half a century, using the highest quality materials and a highly secretive manufacturing process. This commitment to quality results in a set of strings that not only sound fantastic but also last for years, keeping your bass sounding its best gig after gig.

At the heart of these strings is the Monel 400 alloy tape, which is wound on a hex core. This alloy contains five times more nickel than stainless steel, producing a warm, punchy tone with incredible sustain and clarity. The flatwound construction adds to this by providing a smooth feel and thumpy tone that is ideal for everything from jazz to rock.

The standard 45-105 gauge of these strings makes them a great choice for bassists transitioning from roundwound strings. The lighter gauge on the E and A strings ensures a comfortable feel, while the heavier D and G strings provide a solid fundamental. This balanced set is versatile enough to suit most playing styles and music genres.

Each set of strings also comes with a recycled nylon gig bag for easy transportation and storage. This environmentally-friendly bag is designed to keep your strings safe from damage, ensuring they stay in top condition for longer.

Great flats!

My string of choice for my Precision bass and Cort fretless. They get me that Roger Waters tone I need and last forever. The only downside is they're a bit high on tension for my Jazz bass. I use the softer D'Addario Chromes for that, but for some reason the Chromes feel like they're about to fall off the Precision. The Rotosounds on the other hand are nice and tight.

Bad Flats

Simple as that, really high tension even for flats, rough wrap for flats. They feel like rubberbands. They are also pretty bright for flats. Good durability, bad everything else.

Rotosound RS77 LD

Deep, low growly bottom end and very well defined. Certainly not very bright. If you're looking for bright, you probably wouldn't be looking at flatwounds.

diego_chang

It depends on you taste

These strings have an incredible warm sound and still pack a bit of punch. Poorly enough I still prefer roundwounds on my fretless because they play much easier and they even on fretless have a much brighter sound.

LoMenzo's gear page reads:

"No Roto's, no show!!! I haven't played or recorded with any other string since 1974, that's a fact! I started out on their "Flat Wounds" then moved on to the standard "Swing Bass" stainless steels. Since the late 1980's, I've been using the "Billy Sheehan" signature set (see a pattern here?). They feel more balanced in my hands and that heavier E string really takes the hall!"
