The Best Guitar Strings

Gauge is just the string's thickness, measured in thousandths of an inch. A ".010" string is ten one-thousandths of an inch across; a ".046" is forty-six. A set is named after its thinnest string (the high E) and its thickest (the low E) — "10-46" means the high E is .010" and the low E is .046".

Thinner strings need less finger pressure to fret and bend, which is why lighter gauges suit beginners and lead players who bend a lot. Thicker strings carry more tension at the same pitch, which gives more volume, sustain, and low-end weight, but takes more finger strength and can make a poorly set-up neck buzz or need a truss-rod adjustment. There's no universally "correct" gauge — it's a trade-off between playability and tone, and most players settle on one gauge and stay there for years.

Both are wrap-wire alloys used only on acoustic strings, wound around a steel core. Phosphor bronze adds phosphorus to the copper-tin bronze mix, which D'Addario markets as delivering a warmer, more balanced tone that ages gracefully. 80/20 bronze (roughly 80% copper, 20% zinc) is the older alloy, and D'Addario itself calls its 80/20 set the brightest in its acoustic line — more sparkle and projection when new, but that top-end shine fades a bit faster as the strings play in.

Neither is objectively better; it's a matter of whether you want a warmer, longer-lived voice or a brighter, more immediate one. If you're not sure, phosphor bronze is the safer first choice — it's what the large majority of factory-strung acoustics already wear.

A coated string has a microscopically thin polymer layer over the wrap wire. Elixir, which pioneered the category, describes its Nanoweb coating as covering the entire string, including the gaps between windings where sweat, skin oil, and dust normally collect and deaden the tone. The upside is real: on r/Guitar and r/AcousticGuitar, players who play daily consistently report going a month or more between changes with a coated set, versus two to four weeks uncoated.

The downside is price — a coated set typically costs about twice as much as an uncoated one — and a small number of players say the coating changes the string's texture slightly under the fingers, especially right out of the pack. If you play often and hate restringing, coated pays for itself. If you play occasionally, or you want the rawest tone the moment strings go on, uncoated is the simpler, cheaper choice.

Acoustic strings use a bronze-alloy wrap (phosphor bronze or 80/20 bronze) over a steel core, chosen because that alloy resonates well and projects loudly with no amplification. Electric strings use nickel-plated (or occasionally pure nickel or stainless) steel wrap wire instead, because an electric guitar's pickups work by sensing a magnetic disturbance from the metal moving above them — bronze doesn't respond to a magnetic pickup the way steel does, so bronze acoustic strings simply won't drive an electric guitar's tone properly.

Electric string gauges also tend to run lighter overall, commonly 9s or 10s, since there's no acoustic soundboard that needs heavier strings to drive it. If you're restringing a guitar you didn't set up yourself, check whether it's acoustic or electric before buying — the two string families aren't interchangeable.

Start with what you play. On acoustic, D'Addario EJ16 is the safe, warm, inexpensive default; reach for D'Addario EJ11 if your guitar sounds a little dull and you want more brightness for the same price; step up to Elixir Nanoweb Phosphor Bronze if you're tired of restringing every few weeks.

On electric, Ernie Ball Regular Slinky (10-46) is the standard, go-anywhere gauge; Ernie Ball Super Slinky (9-42) is the easier-on-the-fingers choice for beginners or smaller hands; and Elixir Nanoweb Electric is the coated option for players who'd rather pay more and restring less.

There's no fixed schedule — it depends on how often you play and how much your hands sweat. Reports on r/Guitar cluster around every four to eight weeks for players who practice most days with uncoated strings, stretching to every two or three months for casual players, and to several months for coated sets. The clearer signal than the calendar is the strings themselves: look for visible grime or discoloration in the winds, a flat or "thuddy" tone that doesn't brighten back up after tuning, strings that won't hold pitch, or actual rust. Any one of those means it's time, regardless of how many weeks it's been.
