Detail 02
Easier to fret and bend, kinder to the fingertips. Less tension means less volume and a thinner low end than mediums.
Detail 03
For steel-string acoustic only. Will not work on a classical or nylon-string guitar.
Detail 04
Cheap per set, which suits 80/20 since these reward frequent changes rather than long life.
Detail 05
Standard for steel-string acoustics; seats under the bridge pins the usual way.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
80/20 is brighter and more scooped, with crisp highs on a fresh set. Phosphor bronze is warmer in the mids and holds its tone longer before dulling.
Light acoustic sets typically run .012 on the high E up to .053 on the low E, though exact gauges vary by maker.
No. These are bronze-wound steel strings for steel-string acoustics. A classical guitar is built for nylon and steel strings can damage it.
80/20 bronze oxidizes faster than phosphor bronze. You get more brightness up front and less of it after a few weeks of playing.
