At Thomastik-Infeld, they don't make any "all-purpose" guitar strings. Instead, they build highly engineered, specialty products that fulfill specific needs. Plectrum strings resonate with a warm, soft tone reminiscent of a classical guitar. They are specifically engineered for situations where a mellower sound is desired. Plectrum Strings also combine the use of flat and wound round technology to help reduce string tension, which can prolong the life of valuable vintage instruments.

Just like their fine orchestral strings, Plectrums have a fabric or "silk" inlay between the core and the windings. This technology reduces "off-color" harmonics, by favoring the even-order harmonics that sound more complementary and musical. The treble strings are made of brass-plated steel, a costly method that extends string life significantly. Austrian precision doesn't just mean engineering accuracy -- it sounds good too!
