Thomastik Peter Infeld 4/4

A revolution in tonal sound and color for the discerning musician, Peter Infeld (PI) strings produce a rich spectrum of sound colors, the perfect blend of power and elegance, and a wide dynamic range. The strings deliver instant bow response as well as superior tuning ability. The soft left-hand feeling brings out the best in you and your performance. Choose from tin, gold, and the unique platinum plated, and thus very powerful E-strings, and the aluminum or silver wound D-strings to achieve a made-to-measure sound for each individual instrument and player.
