A smooth phosphor bronze set made for resophonic guitars, with reduced finger noise for recording and slide. It is not an ordinary flat-top guitar set by gauge or design.

Overview

A slide player or recording guitarist gets reduced finger noise from this half-round phosphor bronze set, which is precision ground to a semi-flat surface. Each string has a high-carbon steel core under phosphor bronze wrap wire.

Smoother feel and a quieter playing experience are the reasons to look at it, with the tone and tension of a standard resophonic set. Recording and flat-picking are the named uses. It is a six-string set sold for resophonic guitars, so it is a narrow choice.

Who it's for

Resophonic and slide guitarists who need less finger squeak while recording or flat-picking. Players with a regular steel-string acoustic should check gauge fit first, and anyone else should choose a regular-surface set.

Pros and cons

Pros
  • Reduced finger noise
  • Smooth, semi-flat surface
  • Phosphor bronze tone
  • Stable tuning claimed
Cons
  • Resophonic fit only, per the listing
  • Item type entry reads upright bass, which is wrong

Performance notes

Round-wound strings are precision ground and polished, which flattens the outer surface without losing the phosphor bronze tone and sustain. That smoother surface reduces finger noise against the winding. Tension matches the standard resophonic set it was based on.

Frequently asked questions

Will the D'Addario EFT13 fit a resophonic guitar?

Why does the listing say upright bass?

The item type entry reads acoustic upright bass, which conflicts with the six-string guitar set shown elsewhere. Go by the set name and title.
