Choosing your Coruss bow
What is the difference between Carbon, Premium Hybrid and Signature bows?
Carbon bows combine a woven carbon stick with Coruss Bow Hair. They offer stable handling, reliable performance and a modern choice of colours.
Premium Hybrid bows feature a carbon core covered with a wood-based fibre and finished to create a traditional wooden appearance. They combine the stability and performance of carbon with a more traditional look.
Signature bows are crafted from pernambuco and finished with refined materials, including silver fittings and an ebony frog. They are designed for musicians looking for a traditional, high-end bow fitted with Coruss Bow Hair.
Are Coruss bows suitable for advanced and professional musicians?
Yes. Coruss bows are played by musicians of different levels, including advanced and professional players. The best model depends on your instrument, playing style, preferred balance and the response you are looking for.
How do I choose the correct bow size?
Choose the bow size that matches the size of your instrument. If you are unsure, check the label inside your instrument or ask your teacher or luthier before ordering.
You can also contact us with the type and size of your instrument, and we will help you choose.
What is the difference between French and German double bass bows?
French and German double bass bows are designed for two different bow holds.
Choose the model that corresponds to the technique you use. If you are unsure, ask your teacher or luthier before placing your order.
Are Coruss bows made without animal-derived materials?
Yes. Coruss bows and Coruss Bow Hair are designed without animal-derived materials.
Coruss Bow Hair
What is Coruss Bow Hair made from?
Coruss Bow Hair is made in France from a highly resistant technical fibre developed specifically for bowed string instruments.
It was created with musicians and luthiers to provide reliable grip, stability and playing comfort.
How is Coruss Bow Hair different from horsehair?
Traditional horsehair naturally reacts to humidity and temperature changes. Coruss Bow Hair is far less affected by changing atmospheric conditions, helping the bow maintain more consistent tension and performance.
It is also highly resistant, long-lasting and made without animal-derived materials.
Does Coruss Bow Hair sound different from horsehair?
Coruss Bow Hair is designed to provide the familiar grip and response expected from traditional bow hair.
As with any rehair, the final result also depends on the bow, the instrument, the quantity of hair, the tension and the amount of rosin applied. A short adjustment period may sometimes be necessary.
Is Coruss Bow Hair affected by humidity and temperature?
Coruss Bow Hair is far more stable than horsehair when exposed to changes in humidity and temperature.
This helps maintain more consistent tension in dry, humid, hot or cold environments.
How long does Coruss Bow Hair last?
With regular use and proper care, Coruss Bow Hair can often last for around two years.
Its lifespan depends on playing frequency, technique, maintenance and the condition of the bow.
Do the different colours affect the sound?
All Coruss Bow Hair colours are designed to provide the same core performance.
The final sound and response depend primarily on the bow, instrument, setup, tension and rosin application rather than the colour of the hair.
How much Coruss Bow Hair should I order?
Our 10 g packs are suitable for violin, viola and cello rehairs.
Our 15 g packs are recommended for double bass bows.
The exact quantity used for one bow depends on the ribbon width, bow model and the luthier’s preferred setup.
Rosin and care
Does Coruss Bow Hair require rosin?
Yes. Coruss Bow Hair requires rosin to grip the strings.
Apply a small amount gradually from the frog to the tip. Too much rosin can create dust, a scratchy sound or a slippery, soapy feeling.
Which rosin should I use?
Coruss Rosin is specifically designed for Coruss Bow Hair and is our recommended option.
Other rosins may work, but their texture and level of grip can produce different results.
My bow produces little or no sound. What should I do?
New Coruss Bow Hair requires rosin before it can properly grip the strings.
Apply a small amount gradually along the full length of the hair, then test the bow. Repeat only if necessary and avoid applying a large quantity at once.
If the problem continues, please contact us so we can help identify the cause.
My bow has lost its grip or sounds scratchy. What should I do?
The hair may have accumulated too much rosin, dust or residue.
Clean the hair carefully with isopropyl alcohol, avoiding all contact with the stick, frog and varnished surfaces. Allow it to dry completely before applying a very small amount of fresh rosin.
How should I care for my bow?
Loosen the bow after every playing session and store it inside its case.
Avoid prolonged exposure to direct sunlight, heaters, extreme temperatures or excessive moisture. Clean rosin dust from the stick and instrument regularly with a soft, dry cloth.
Can Coruss Bow Hair be fitted by any luthier?
Yes. Coruss Bow Hair can be fitted by a professional luthier or bow maker.
The installation technique differs slightly from horsehair. The fibre should not be exposed to a flame or direct heat. We can provide technical instructions to your luthier if required.
Why does the hair ribbon look narrow or twisted?
The hair ribbon may have rotated while the frog was being tightened or handled.
Loosen and carefully unscrew the frog, rotate it one full turn to return the ribbon to a flat position, then reinstall and tighten it gently. If you are unsure, contact us or ask a luthier for assistance.
