Description
If you’re the type who swaps strings before a gig rather than after one goes dull, this 12-pack of Ernie Ball 2148 Earthwood Phosphor Bronze sets is built for your habit. Each set wraps a phosphor bronze alloy — 92% copper, 7.7% tin, 0.3% phosphorus — around a tin-plated hex-shaped steel core, the combination responsible for that light orange-gold hue and the mellow, ringing voice these strings are known for. Clarity stays present through every strum, whether you’re fingerpicking or flatpicking hard.
Buying a dozen sets at once means you’re never caught with corroded, lifeless strings the night before a show or a studio session. Fresh strings simply feel different under the fingers — brighter attack, better intonation, and that satisfying snap that fades a little more with every practice session. Keep this pack in your gig bag and restring on your schedule, not when your old set forces the issue.
