Thomastik-Infeld Plectrum acoustic guitar strings combine bronze-like warmth with easy playability — think classical tone with a jazz-esque feel. These strings boast a low-tension, hybrid arrangement of flatwound A, D, and G strings with a roundwound low E. You also get precise overtone balance thanks to silk inlays. The guitarists here at Sweetwater have found that Plectrums can extend the playing life of your vintage instrument, as these strings’ lower tension compensates for weak bracing and other issues that can arise with age. If you want to coax the best sound possible out of your acoustic guitar, give Thomastik-Infeld Plectrum strings a try — these strings are top shelf all the way.
