Choose the CodaBow Joule carbon fiber bow for violin, viola, or cello for an empowering performance. Now completely customizable. Delivering a brilliant, strong tone, the Joule is ideal for electric instrument musicians and extended instrument musicians.

• Balance: Center-Tip
• Weight: Medium-Heavy
• Action: Moderate
• Stiffness: Medium-Stiff

In science, a joule is a unit of energy, which is precisely what you can expect when playing with a Joule carbon fiber bow. We named the bow after the 19th-century English physicist whose work set the foundation for today’s understanding of energy. The bow’s design intends to generate more power and energy than any other conventional bow of the same weight.

What Makes the Joule Bow So Powerful?

Heavy bows give a fuller, bigger sound by maintaining a better grip on your strings. While the Joule is heavier than the average violin, viola, or cello bow, the bow’s weight isn’t the only attribute that contributes to its power across extended ranges.

Innovative Shaft Design

Unattainable with traditional materials, the innovative design of the Joule's shaft adds more mass to critical performance areas while preserving a balanced weight and comfortable flexibility. This unique design allows the bow to grab the string and speak effortlessly, whether you're playing deep, whole tones, or percussive chops.

Within the shaft resides a composite acoustic core made of durable carbon fiber. The resulting architecture gives this design impressive power that belies its quickness and facility.

Optimized Frog and Hair Length 

The Joule boasts a powerful resonance on the bottom strings and strong projection across all ranges. The shorter frog and longer hair allow for exploration in more aggressive and demanding styles and set-ups. The Turbo Xebony® Frog design offloads weight under the hand to provide more space for bowing techniques at the frog.

Layered Diamond Weave

Multiple layers of our pioneering Diamond Weave technology give the Joule high torsional strength while preserving desired longitudinal flexibility. This enhancement allows you to command the string without collapsing the bow to retain the nuance of expression. 

Joule reviewers back us up! One Portuguese violin player with more than 50 years of experience reported that the Joule gave his playing "new expression and performance capabilities" compared to the difference in balance from a classical bow. 

Ready to Rock

Musicians of electric instruments and 5-6 string instruments appreciate the Joule's capabilities and delivery. Its features align for best-in-class bluegrass, old-time, and fast jam performances. Joule reviewers report pulling "a great tone" out of their acoustic fiddles. Others rejoice that they're finally able to nail a specific tone. One CodaBow violinist shares, "The violin Joule has just the right weight for the upper and lower strings on my 5-string, and I don't have to work as hard to get the C-string tone I've been looking for."

Durable Enough for a Lifetime

All high-wear components (including tip plate, tip wedge, and button bearings) are precision-made using industry-leading composite materials to ensure a lifetime of worry-free play.

Sustainably Crafted 

The CodaBow Joule carbon fiber bow holds the GlobalBow® designation. This designation ensures that the bow contains no endangered, monitored, or regulated species (wildlife or fauna) and can pass worry-free through international Customs. Practice in Los Angeles, perform in Mexico City and play wherever you like when you have a Joule violin, viola, or cello bow.
