Can You Put Steel Strings on a Nylon Guitar? Thomastik-Infeld KF110 Flatwound Test

Can you really put steel strings on a classical / nylon string guitar without damaging it? In this video I test the Thomastik‑Infeld KF110 Classical S Precision Flatwound steel strings on my Taylor Academy 12e‑N and share what they actually sound and feel like. I’m a professional guitarist and vocalist with over 50 years of experience, and I love testing unusual string combinations so you don’t have to risk your own guitar. These Thomastik‑Infeld KF110 strings are designed specifically for classical guitars, with lower tension than normal steel strings and a smooth flatwound feel.
