We have bundled together the most popular kinds of Equal Tension tenor viol strings and offer them in a standard set for ease of ordering. The set consists of:

  • g-1 Treble gut
  • d-2 Treble gut
  • a-3 Lyon gut
  • F-4 Pistoy gut
  • C-5 Gut/silverplate-wound
  • G-6 Gut/silverplate-wound

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.

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.


Academie strings are manufactured 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.

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 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.
