Three sets. Light gauge, 12 to 53. Phosphor bronze over a hexagonal high-carbon steel core. Made in New York. $8.30 a set.

This is the string most steel-string acoustics are sold with, bought in the quantity they are used. There is very little more to say about it, and that is the point of the page.

What is worth setting out is the three-way comparison this shelf now makes possible, because all three are the same maker, the same 12-53 gauge and the same hexagonal core:

alloyper set
EJ16, singlephosphor bronze$9.99
EJ16-3D, threephosphor bronze$8.30
EJ11-3D, three80/20 bronze$6.66

So the question is not which is better but which of two things is being bought: three sets of the default, or three sets of the bright alternative for $1.64 less each.

Phosphor bronze is warm and balanced in D’Addario’s own words, and the alloy it pioneered in the 1970s. 80/20 bronze — on the other three-pack here — is bolder and brighter, from the 1930s, and loses its brightness sooner. A guitar that came from the factory with phosphor bronze will sound like itself on these, and different on the 80/20.

The hexagonal core is the construction both share and most of this shelf does not publish: six flat faces for the wrap wire to bite into rather than a round core it can creep along, which is why the string settles into tune sooner. Three of the six strings on this shelf publish a core shape and all three are D’Addario.

And the reason to buy three at once is on another page on this shelf, in its own words: strings die quietly — tone goes first, then tuning stability — and a set lasts one to three months at a few hours a week.

The questions players ask

Why pay $1.64 a set more than the 80/20?

For a warmer voice and a longer one. The two packs on this shelf are the same gauge, the same hexagonal core and the same maker — the only variable is the wrap. Phosphor bronze is warm and balanced and holds that character; 80/20 bronze is brighter when new and fades faster. Most acoustic guitars leave the factory with phosphor bronze, which makes this the string that keeps a guitar sounding like itself. The 80/20 is the deliberate change, not the default.

Three sets or one?

Three, on a guitar that is played. The page for another string on this shelf states the consumable case: a set dies quietly — tone first, tuning stability second — and lasts one to three months at a few hours a week. Three sets is roughly a year and costs $8.30 a set against $9.99 for one. The single set is for a guitar restrung annually, or for trying an alloy before committing to three of it.

    • Publishes a gauge — 12-53 — where the two strings already on this shelf publish none
    • Publishes the core shape, which is what holds the wrap in place and decides whether a string settles
    • One set, where the same string in a three-pack works out at $8.30 a set

    Best for: A single restring on a steel-string acoustic, where the gauge should be the standard one.

  • D'Addario Pro-Arté nylon classical guitar string set

    Best for: A classical or concert guitar — and no other kind.

  • Dragonpad USA 6-inch dual-layer pop filter with clamp

    Dragonpad USA 6 in studio filter

    The only filter here that publishes how it works: two layers of nylon mesh with an air gap between them, six inches across, on a metal gooseneck with a tension screw.

    Layers
    Two layers of nylon mesh with an air gap between them, which Dragonpad states reduces popping and lisping without dulling the sound — one of two filters here to publish a layer count
    Diameter
    6 in — the only filter diameter published on this shelf
    Gooseneck
    Metal, which Dragonpad states is strong enough to hold position and still easy to adjust
    Mount
    A universal bracket with a tension screw, stated to fit virtually any microphone or stand
    Stated purpose
    Plosives and lisping, and keeping saliva off the capsule — Dragonpad notes that saliva contains corrosive salts
    Clamp capacity
    Dragonpad puts nothing in writing on this. One filter on this shelf publishes shafts up to 18 mm (0.71 in)
    Material
    Nylon mesh. One filter here is metal, one is foam and one offers all three

    B00XQFOSZE
    EAN
    0634972184415
    • Publishes the mechanism: two layers of mesh with an air gap, which is how a pop filter actually works
    • The only published filter diameter on this shelf — six inches
    • No clamp capacity published, so the stand question is still open

    Best for: A close vocal where the filter should be big enough to stay in front of a moving head.
