D'Addario Acoustic Guitar 25 Pack Phosphor Bronze , .013 - .056, EJ17-B25

D'Addario EJ17-B25 Phosphor Bronze Acoustic Guitar Strings, Medium, 13-56, 25 Bulk Sets

EJ17s offer heavier tension resulting in a bolder, more resonant acoustic tone with higher resistance for heavy strumming and flat-picking.

Phosphor Bronze was introduced to string making by D'Addario in 1974 and has become synonymous with warm, bright, and well-balanced acoustic tone.  D'Addario Phosphor Bronze strings are precision wound with corrosion resistant phosphor bronze onto a carefully drawn, hexagonally shaped, high carbon steel core.  The result is long lasting, bright sounding tone with excellent intonation. Also available in 3D packs.

D'Addario's most popular choice for heavy strumming, flat-picking and resonant, projecting tone in a convenient bulk pack of 25 sets

Preferred for its warm, bright, and well-balanced acoustic tone

Bulk shop packaging is ideal for workbenches or anywhere bulk packaged strings are needed

IMPORTANT - These are not individually packaged sets. They are convenient bulk packs (25 strings each) of individual gauges. To make up a set, remove one string from each of the bulk compartments. They are intended for the needs of repair shops but are great for the individual player as well.

In 1974, D'Addario pioneered the use of phosphor bronze wire for the winding of acoustic guitar strings. D'Addario phosphor bronze strings were an instant and enduring success. A more costly alloy, phosphor bronze was widely known as a durable, long-lasting material used in machine bushings and bearings. After months of searching, a wire company was located that agreed to make sample wires for testing on music strings. The results made history. D'Addario phosphor bronze strings are bright sounding and retain their brilliance longer than other bronze and brass alloys.

Round wound phosphors are available in 6 different gauges for 6 string guitar, 3 gauges for 12 string, and 4 gauges in the Flat Tops series. Flat Tops are round wound phosphor bronze strings that are lightly polished to reduce finger noise and fret wear, and are an excellent choice for noise-fee recording.
