D'Addario

D'Addario EJ17 Phosphor Bronze Acoustic Guitar Strings Medium 13-56 3 Pack

SKU CH-KX43-F534S

Medium-gauge 13-56 phosphor bronze acoustic strings in a three-pack for fuller tone and drop-tuning stability

  • Medium 13-56 gauge delivers fuller tone and stronger projection
  • Phosphor bronze wrap on hex-core steel wire resists corrosion for lasting brightness
  • Precision winding ensures accurate intonation across the fretboard
  • Three-set pack keeps fresh strings ready for every session
  • Trusted since 1974 by players who demand consistent performance

Phosphor Bronze Medium Gauge Set

The D'Addario EJ17 set contains three packs of acoustic guitar strings built with phosphor bronze wrap wire on a hexagonal high carbon steel core. Gauges run from 13 to 56 and are designed for players who want robust volume and balanced warmth. The medium tension suits standard and altered tunings alike. D'Addario has manufactured strings since 1974.

Sustained Tone And Intonation

Precision winding keeps each string bright and clear through extended playing sessions. Corrosion-resistant phosphor bronze slows tonal decay caused by sweat and humidity. The hexagonal core locks the wrap wire in place, preserving intonation across the fretboard. Players report consistent projection even after hours of heavy strumming.

Check Scale Length And Nut Slots

Verify that your guitar’s scale length and nut slots accommodate the 13-56 gauge range without binding. Heavier tension may require a truss-rod adjustment on instruments set up for lighter sets. Ensure the bridge pins and saddle can handle the increased downward force. Buyers who prefer light tension or extra-light sets should consider a different gauge.

Questions about this item

How much heat or noise do the D'Addario EJ17 strings add during long playing sessions?

The phosphor bronze strings produce no heat or electronic noise; only the natural acoustic vibration of the wound medium gauge wires is heard.

What must I already own to use this 3-pack of EJ17 sets?

You need a standard acoustic guitar with a bridge and tuning machines that accept ball-end strings sized from .013 to .056 inches.

Will the .013-.056 medium gauge EJ17 set work on a vintage guitar built before 1974?

Yes, the phosphor bronze wrap on a hexagonal high-carbon steel core fits any traditional acoustic bridge and tuners, though higher tension may require a setup check.
