D’Addario EJ11-3D

Three sets of light-gauge 80/20 bronze at $6.66 a set — the lowest price per set on this shelf — in the bolder and brighter of the two acoustic alloys, created in the 1930s.

Quantity
Three sets — which works out at $6.66 a set, the lowest price per set on this shelf
Gauge
Light, 12-53 — the same gauge as the two phosphor bronze sets here, so the comparison is purely about alloy
Wrap wire
80/20 bronze, which D’Addario states gives a bold, bright sound with crisp projection — the other acoustic alloy, against phosphor bronze’s warmth
Core
A hexagonal high-carbon steel core, precision wound
Origin
Created in the 1930s by John D’Addario Sr. and the guitar maker John D’Angelico — the earlier of the two dates published on this shelf
Made in
The USA, drawn at D’Addario’s New York facility
Packaging
A recyclable VCI bag with a Players Circle code
Instrument
Acoustic. Not for the electric or classical guitars this shelf also serves

  • The lowest price per set on this shelf — $6.66, against $8.30 and $9.99 for the same gauge
  • The same 12-53 gauge as the phosphor bronze sets here, so the only variable is the alloy
  • 80/20 bronze is brighter and loses its brightness faster than phosphor bronze

Best for: A played acoustic whose owner has decided they want bright rather than warm, and wants a year of strings.

Three sets. Light gauge, 12 to 53. 80/20 bronze over a hexagonal high-carbon steel core. Created in the 1930s by John D’Addario Sr. and the guitar maker John D’Angelico. Made in New York.

The arithmetic is the first thing worth doing, because the prices on this shelf are misleading.

what you seewhat a restring costs
EJ16, one set, $9.99$9.99
EJ11-3D, three sets, $19.99$6.66
EJ16-3D, three sets, $24.90$8.30

The cheapest set on this shelf is inside the middle pack. A reader scanning three prices sees them in one order; a reader costing one restring sees them in another.

The second thing is the alloy, and it is the only real decision here. 80/20 bronze — eighty per cent copper, twenty per cent zinc — is bold and bright, with crisp projection. Phosphor bronze, on the two other sets on this shelf, adds phosphor and sounds warmer and more balanced. Both come from the same maker, at the same 12-53 gauge, over the same hexagonal core, so a player can change exactly one variable and hear what it does.

Two things follow. First, 80/20 is the original — the 1930s against the 1970s, and the earlier of the two dates published on this shelf. Second, it loses its brightness faster: the quality that makes it appealing when new is the one that goes first, which is an argument for buying three sets rather than against it.

The page for another string on this shelf makes the consumable case in its own words — tone goes first, tuning stability second, and a set lasts one to three months at a few hours a week. Three sets is a year.

What buying three of one alloy commits you to is the voice, before hearing it on your own guitar. The single phosphor bronze set at $9.99 is the cheaper experiment.

The questions players ask

80/20 or phosphor bronze?

Bright or warm, and that is genuinely all. 80/20 bronze is eighty per cent copper and twenty per cent zinc — bold, crisp, with projection that fills a room, in D’Addario’s words. Phosphor bronze adds phosphor to the alloy and sounds warmer and more balanced; it is also what most acoustic guitars ship with. Both are on this shelf at the same 12-53 gauge from the same maker with the same hexagonal core, so a reader can change exactly one thing. The practical difference beyond tone is that 80/20 loses its brightness faster.

Why is the cheapest set in the most expensive pack?

Because the arithmetic on this shelf runs the other way from the sticker. A single set is $9.99. The phosphor bronze three-pack is $24.90, which is $8.30 a set. This 80/20 three-pack is $19.99, which is $6.66 a set — the lowest on the shelf. A reader comparing the three prices on the page sees 9.99, 19.99 and 24.90; a reader comparing the cost of one restring sees the order reverse.
