When you start playing the upright bass you have so many decisions to make in terms of which instrument to choose and which accessories including string.

As you start to gain confidence with your instrument and enhance your musical abilities you reach a point where accessories influence the sound you are able to produce with your instrument much more.

At this point it’s important to review what strings are out there not just in terms of the material used but the manufacturing process.

The Corelli strings are just one of many options for bassists but there are multiple series produced by the company and within each series multiple levels so it can still be a bit confusing.

To help you understand which one is best suited for your situation we’ve put together some information in this Corelli bass strings review about the origin of the company, what techniques and technology they use in developing their strings, and what the different labels in series really mean.

Savarez company

The Corelli strings are made by the Savarez company out of France.

This family began very early on moving from Italy to Paris where they started manufacturing gut strings by hand and using the winding process which at the time was incredibly new although today is something you will see in every string manufactured on the market.

From 1880 until 1930 they started using new types of silk and steel to modify the different strings they made by hand and things like brass and bronze to use as the winding for their special strings.

In the 1930s technological developments including modern techniques for grinding material, sizing it, and controlling the development of an equally refined string all the way across the length of the string helps the company to capitalize upon nylon.

They started making strings for bowed instruments and became quite popular for guitars.

In the 1950s the company started creating strings using a rectified nylon trouble and spun nylon.

While today it’s quite common to see three different levels of tension among string manufacturers, this company was the first to introduce that.

The Corelli String line was created in 1980 when it was launched for all manner of acoustic, bowed instruments.

When to use Corelli

The Corelli strings are quite popular for upright bassists who want high quality but light weight.

This particular line of strings was made famous by a solo bassist from France who used them regularly during performances.

They are a super light type of string which means they are much easier to play without having to press your bow too hard on the strings or push too firmly with your fingers.

The strings also peak slightly easier if you are using your boat compared to other strings because they are thinner which is in large part what makes them lighter. 

The thin string design does come with a downsides though.

Firstly, being a smaller string they do lack the power or projection of regular strength like Thomastik brands.

They are very popular for recital performances and solo performances.

However, if you are part of a group and you need extra projection or sound so that your instrument is heard over other stringed instruments, these strings might lack the power you need.

Which series to choose

If you decide that it’s worth the investment because it suits your situation you have to examine the different series that they offer. 

370 Series

These strings are strong and supple, but just as lightweight as you would expect from Corelli.

They are made with tungsten steel, a material that is regarded for its durable tensile strength.

It has narrow gauges, no matter the three standard gauge sizes you choose, when compared to strings made of other material. 


So within this series you have medium, which is a misleading name as it is the lightest gauge they offer.

It is perfect for soloists who need to perform without trying to be heard over others.

It is also suitable for lightly constructed acoustic instruments which might be stressed by a heavier string.

The medium string is the only one you can get in fractional sizes, so if you have a smaller child playing the upright bass in need of a fractional set, this is the one to choose. 


This is the medium level tension, in spite of its name. This is better for players who are doing solo work but want a more versatile string.


This is their heaviest tension for the 370 series. It is best for players who want a hybrid use string.

360 Series

These strings are sometimes called the Solo Tuning strings. They are also made of tungsten.

They are lightweight, as all Corelli strings are, but they are strong too. The design for this series is finely gauged, specific for solo tuning. 


This is the first tension they have, which is the lower tension. In this series, there are only two levels. 


This is the higher tension string in the series.You can do solo tuning for A-E-B-and F#.

380 Series

This series is for orchestra tuning. Thicker than the others, it is as close as you will find in the Corelli line to the industry standard for upright bass strings.

These are wrapped in nickel. 


This is still the lower tension string.


This is the higher tension string with orchestra tuning for G-D-A and E.


This is a special string that has a stronger sound with a rich tone, and it is recommended for acoustic jazz music, where you need the best possible acoustic output. 

390 Series

This series is intended for solo tuning. This line has a nickel wrapping and is also thicker than the 370 series.

Still, it is easy to play and best for solo work.

These strings are recommended for performers with smaller hands, or those who just want an easier string to play, one more similar to the industry standards. 

Corelli Bass Strings review: Options for you

Now that you understand all the terminology, it’s time to review different products and pick one that’s going to suit your situation best.

To help you with that, the section below will look at some of their different products and different series to compare the features.

It’s important to always consult an industry professional before using any new product with your instrument.

CUERDAS CONTRABAJO – Salvarez (Corelli 300/A) (Juego Completo/Niquel/Orchestra) Medium Bass 1/2

This is the Corelli 300/A which is a medium bass ½. It is an orchestra series, with a medium gauge for easy play, especially as a beginner. It is made with nickel.

They are the smallest you will find from the manufacturer, but they are perfect for anyone using a smaller, ½ size instrument. 

It is even smaller than the others, with the thinner gauge being the medium size, so remember that if you opt for medium you are opting for the lowest tension they make.

Beyond that, these are well suited to smaller players and will bring about the same rich tone as the other series.

They are still, suited to solo performances and practice rather than group practice because they won’t be as loud.

This string, like the others, is made with computer laser technology which provides a high precision string diameter.

This thinner gauge makes the strings better at maintaining tuning accuracy, makes them more flexible, and therefore faster to respond to your movements. 

With this one string, you can replace what you have by mixing and matching until you find the right sound.

  • Thinner gauge for easy response and playability
  • Part of the 300 series
  • Made with computer laser technology for the winding and composition, so better tuning accuracy


  • Meant for ½ size bass which not everyone has

Corelli Orchestral Tungsten Series Double Bass String Set 3/4 Size Medium Ball End

These are part of the 370 series. They are meant for a full size ¾ double bass. The strings are medium size with a ball end.

Made from the orchestral tungsten series, they are unique designed thanks to the winding process and the technology Corelli uses for the composition. 

This process provides a high precision string diameter thanks to the computer laser technology and that purportedly gives greater tuning accuracy.

Therefore, the strings will remain in tune, longer.

The strings also have a thinner gauge which makes them more flexible, with a faster response to your fingering. They are also easier to play being so thin and flexible. 

Part of the Orchestral Tungsten Series, these strings are an ideal set to keep if you want the tungsten material and medium tension.

The 370 of course is the smallest, thinnest they have and remember that this says “medium” but for the Corelli line, medium tension is actually the lowest tension level.

  • 370 series
  • Medium size, fo ¾ instrument
  • Unique winding process
  • Tungsten material


  • Thinner gauge, not all players appreciate

Corelli Strings For Double Bass Orchestra tuning 1/4 Size G Nickel

This string is meant for ¼ size instruments. It is part of the Orchestral set, but this version is the Forte, their strongest and thickest string. It is nickel, a single G string, part of the 380 series. 

This Orchestra tuning series as mentioned is thicker than the 370 series listed above and it’s really as close as you’re going to find out of the Corelli strings for a double bass that are physically similar to the industry standard in terms of thickness and weight.

They are slightly heavier and slightly thicker than other series produced by the company and they’re wrapped in nickel.

This of course is just the single string but you should remember that the medium is actually the lowest pension they offer while the ForteTX is the highest string tension.

This is the Forte version so it is the highest string tension but you can look for the TX version if you absolutely need that stronger sound with the highest level of acoustic output for jazz music only.

View at Amazon for more information on how this product might work for you.


  • 380 series, thicker than the 370 series but more on point with industry standards for weight and thickness of strings
  • Forte, so the highest level of gauge they produce
  • G string made with nickel winding


  • For ¼ size instruments
