This is a double-length (48", 120cm) treble gut string intended for “Equal Tension” performance practice made with beef serosa available with either a natural or varnish finish. This gut string is available only in the natural color which varies from white to a pale straw hue.

The string comes with plain, unknotted ends. 3-D printed ball ends may be added for an additional charge. If you select the 3-D printed ball end option, the string will come with ball ends on each end. You can cut the string in the middle and install as is your practice. 

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

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.

Beef serosa has a higher tensile strength than does sheep gut, so this string is useful for instruments that require extra durability. If your instrument has a longer string length which puts it beyond the comfortable range for sheep gut strings, the beef gut would be a good choice for string selection as it will stand the strain a little better. Treble gut is processed to be a little harder than other kinds of gut, and it also has a lower twist of about 15 degrees to increase the strength.

Equal Tension is a concept that was used on violins historically. The idea is that each string has the same amount of tension, resulting in equal tension on all strings. The customary way to tension strings is to decrease the tension from the top string, which has the most tension, to the bottom string in decreasing amounts on each string. From the 16th to 19th centuries there are writers who mention or recommend equal tension, and this seems to have been one aesthetic that some players used. Merssene, in the early 1600s, mentioned that violin strings should have equal tension, but that in practice most players used less tension on the lower strings. It may be that the idea of “equal” was an intellectual concept of perfection and that, in practice, players found that lowering the tension on the thicker bottom strings was just more practical. Regardless of the extent of the historical use, many modern players find that this system of string allows a quicker and louder response from the instrument. The extra tension on the lower strings allows the bow to play more on top of the strings resulting in quicker bowing.

Because of the added diameter on equal tension strings, your instrument may need some adjustment at the tailpiece, bridge or nut to allow for the extra mass of the strings. The instrument may also need sound post or other adjustments to bring out the most responsive tone.


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.

    Great string

    These strings work really well on my violin. They last a long time. Sound great and can be played clearly right off the end of the fingerboard. Perfect for early music and more modern compositions alike.

    Equal tension E-1

    I tried the sheep gut E on my Baroque violin and it did not speak with adequate clarity on my instrument. This string however works perfectly.

    a better product

    It seems that strings are a bit stronger than before and produce silky sound. But I am still scary when changing a new E string ^^; Thank you

    Equal Tension Violin E-1

    This string was fitted to a 17th century style pochette that I built for a client. The sound was great, but the string only lasted a day on the first half, and a little less on the second. I ordered a slightly different .58 mm treble gut string, and it has held up very well. I would guess that this string was just the victim of an unfortunate internal or material flaw, as all the other strings I have used from Gamut have been excellent, and I am certain I would try this again.
