A String Pirastro Eudoxa-Aricore 4/4 for Violin

Eudoxa-Aricore is a synthetic A string, not a gut one, and that is exactly the point. Pirastro states it plainly: the core is made from polyester and the string is offered as an alternative to gut core A-strings. Anyone playing gut knows the reasoning — the A wears out first because it takes more finger work than any other string, so a gut second string needs replacing more often than the rest. Article 414231: gauge 13 1/4, aluminium winding, 5.4 kp, ball end, 4/4 size. The factory describes the sound as darker than the regular Aricore A — which is why this string sits so well next to the warm gut D and G of the Eudoxa line.

Polyester Where Gut Gives Up First

In a gut set the A always has the shortest life: the fingers work it harder than any other string and the winding dulls sooner. Eudoxa-Aricore addresses exactly that — a polyester core stands up to daily work longer than sheep gut, so the second string stops being a recurring purchase. Pirastro makes no secret of the trade-off: this is not gut but an alternative to gut, and the line is catalogued as synthetic.

Darker Than The Regular Aricore — Which Is Why It Matches Eudoxa

The factory states that the Eudoxa-Aricore sound is darker than the regular Aricore A. That is not an abstract note: alongside gut D and G wound in aluminium and silver, a bright synthetic A would stand out of the set as a foreign colour. The darker version smooths the crossing through the middle, so the string does not read as a transplant from another line.

5.4 kp And Three Gauges: 13 1/4, 13 1/2, 13 3/4

The line comes in three thicknesses in steps of 1/4 PM: 13 1/4 at 5.4 kp, 13 1/2 at 5.7 kp and 13 3/4 at 6.0 kp. Article 414231 is the thinnest and softest of them. Worth knowing: even this one pulls tighter than the Eudoxa gut A, whose tension runs from 4.5 to 5.1 kp depending on gauge — the synthetic A feels firmer under the left hand and gives the middle of the set a little more resistance.

Specifications

What's Included

The string ships singly, in a branded Pirastro envelope with the article number and gauge printed on the front. There is no Eudoxa-Aricore set — the line exists solely as a single A string.

Who It's For

This A is for the player running gut Eudoxa D and G who is tired of replacing the gut second string, for the violinist who needs dark synthetics rather than bright ones, and for the musician building a hybrid gut-and-synthetic set around one instrument.
