D'AddarioEJ17 Bulk Pack Phosphor Bronze Medium Acoustic Guitar Strings
1/2
Independent shopping perspective
The Korena take
Bulk pack of phosphor bronze acoustic strings in medium gauge. For players or shops that change strings often enough to buy in quantity.
Strong match
Who this is for
- Gigging players who change strings every few weeks
- Repair shops and teachers restringing multiple instruments
- Flatpickers and strummers who want medium-gauge tension
Consider the trade-offs
When to look elsewhere
- Players who change strings once or twice a year
- Light-gauge players who want an easier fretting feel
- Vintage or lightly built acoustics not set up for medium tension
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Medium gauge
Thicker than the common light set. More volume and low end, but noticeably stiffer under the fretting hand.
Detail 03
Bulk pack
Multiple sets in one purchase, so the per-set cost drops. Only worth it if you actually restring often.
Detail 04
Acoustic guitar strings
Bronze wrap is built for acoustic pickup by the top, not magnetic pickups. Not a substitute for electric strings.
Detail 05
EJ17 set
D'Addario's standard medium phosphor bronze set. Consistent across packs, so feel doesn't shift between changes.
Final check
Know before you order
- 01Medium gauge pulls harder than light; your guitar may need a truss rod adjustment
- 02Confirm your acoustic is rated for medium tension before switching up from light
- 03Buy bulk only if you'll use them; strings age in the package over years
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How is this different from buying single sets?
Same strings, bought in quantity. The per-set price is lower. It only saves money if you restring often enough to use them all.
02Will medium gauge damage my acoustic?
Most modern steel-string acoustics handle mediums fine, but lightly braced and older instruments may not. Check with the builder or a tech first.
03How long do strings keep in the package?
Sealed packaging slows corrosion considerably, so stored sets stay usable for a long time. Keep them somewhere dry and away from heat.
04Can I use these on a classical guitar?
No. These are steel strings for steel-string acoustics. A classical guitar is built for nylon and can be damaged by steel-string tension.
