E String Pirastro Gold 4/4 for Violin
The Pirastro Gold E is a plain steel string with no winding, and the maker calls it exactly that — the popular steel E, with a brilliant and powerful sound and a very easy response. Article 315121, mittel gauge at 0.26 mm, 7.7 kp, ball end, 4/4 size. It is the E fitted in the factory Gold set 215021 and at the same time one of the most frequently bought single steel E strings, used both alongside gut sets and as a straight replacement for a worn top string on any 4/4 violin. One thing to be clear about: this steel is not gold-plated — the name Gold refers to the line's label, not to any coating on the string.

🏆 SoundsGood — genuine Pirastro strings only, handmade in Germany.
No Winding Means No Inertia
A plain steel string has no metal layer to get moving: the core answers the bow practically as the stroke begins. Pirastro describes this E as brilliant and powerful with a very easy response, which is why players reach for it when the top lacks definition — short détaché comes out cleaner and high positions stay clear. Against a wound E, plain steel sounds brighter, something the factory states itself when it contrasts the wound and unwound top strings.
0.25 · 0.26 · 0.27 mm — What Each Step Buys You
The Gold E comes in three thicknesses: 0.25 mm at 7.2 kp (article 315111), 0.26 mm at 7.7 kp (315121) and 0.27 mm at 8.5 kp (315131). The step from thin to medium is half a kilopond, from medium to thick almost a whole one, so the strong gauge really does feel noticeably tighter under the fingers. Gauge 0.26 mm is the one in the factory set: the all-round balance between easy response and resistance.
Gold Is The Label, Not A Coating
People regularly search for this string as gold-plated steel, and that is a cataloguing error: the Pirastro Gold E is an ordinary steel string with no gold coating, and the word Gold in the line's name refers to its gold label and branding. Pirastro does make gold-plated and gold-alloy top strings, but in other lines — the Oliv E-goldsteel and the Evah Pirazzi Gold E. If a gold coating is what you need, that is where to look.

Frequently Asked Questions
What gauge and tension is this E?
Mittel gauge, that is 0.26 mm, at 7.7 kp, 4/4 size. The line also offers 0.25 mm at 7.2 kp and 0.27 mm at 8.5 kp.
Is this gold-plated steel?
No. The Pirastro Gold E is plain steel with no gold on it; the name Gold refers to the line's gold label. Pirastro's gold-plated and gold-alloy E strings belong to other lines — Oliv E-goldsteel and Evah Pirazzi Gold.
Ball end or loop end?
Article 315121 is the ball-end version. The same gauge with a loop is 315821; the choice depends on the tuner fitted to your tailpiece.
How does plain steel differ from a wound E?
A winding adds mass and smooths the top slightly, so a wound E sounds warmer while a plain one is brighter with a sharper attack. Pirastro states plainly that the plain steel E sounds more brilliant than the wound one.
Which sets is it fitted in?
The Pirastro Gold sets 215021 and 215022 with a ball-end E. Its 7.7 kp matches the tension of the Eudoxa set's E, so used as a replacement top string on a gut set it changes the character of the sound but not the total tension.
Are these genuine Pirastro strings?
Yes. SoundsGood supplies only genuine Pirastro product, handmade in Germany, in branded envelopes marked with article numbers.
