We have bundled together the most popular kinds of beef serosa Bass Viol strings (48", 120cm) and offer them in a standard set for ease of ordering. The set consists of:

Plain gut strings are available with a natural or varnish finish. Natural strings are hand-rubbed with a light oil. Varnished strings have three coats of finish before being hand polished with the oil. There is an additional charge for varnished strings. The string comes with plain, unknotted ends. Knots may be tied for you, and leather washers added for an additional charge.

Instructions on how to tie a string knot are on the back of each package.


Hand-made in the USA by Gamut Music, Inc., a leader in the revival of early music strings and instruments. Gut strings are not intended to be used with fine tuners or string adjusters, and those devices should be removed before installing the gut string on the instrument.

All Gamut Academie strings (pure gut and gut/metal-wound) are made with beef serosa unless they specifically say "Sheep Gut." All pure gut Tricolore violin and viola strings are made with sheep gut; gut/metal-wound Tricolore and all Red Diamond strings are made with beef serosa.

Gamut gut string gauges are approximate (≈) diameter. Meaning, that while a ≈0.60mm string is polished in the workshop to a diameter of 0.60mm, changes in ambient humidity, temperature, shipping, and storage conditions can cause to string to expand or contract slightly.

Gimped gut strings and custom gauged equal tension strings are gauged with the equivalent-gauge (=) system. This means that the gauge listed, such as =1.50mm, indicates that the string is approximately equal in weight to a plain gut string of that diameter. Of course, because the wire is much heavier than gut, the string will be much thinner than a plain gut string.

More information about Gamut gut strings, string types, gauges, and string tensions can be found on our FAQ/Articles page. Not finding an answer to your question? Please contact us directly:

    Fabulous sound

    I love these strings. The only reason I didn't give them five stars is because I haven't used all the other types of strings for comparison. When I play on them, my instrument sounds much better than my level of skill merits.

    Set Bass Viol 7 strings

    I ordered these strings for my dear friend Daniel Guzman who lives in Mexico City. Daniel, also an excellent luthier always asks for the best quality strings for his instruments and Gamut Music is always his choice. I was very surprised when they arrived, nicely packaged, excellent flawless craftsmanship, and great service from Gamut Music. I am only an occasional customer but I have always been satisfied with my purchases; replacement rosettes, strings and pegs! Thank you.
