These specialized tuning pegs, often found on high-quality guitars, utilize a clamping mechanism to secure the string at the post. This differs from traditional tuning machines which rely solely on the tension of the wound string. A typical example involves a thumbwheel or screw on the tuning peg that, when tightened, grips the string firmly in place.
Enhanced tuning stability is the primary advantage of this design. By minimizing string slippage, they contribute to more precise and longer-lasting tuning, especially beneficial for tremolo use and frequent string bending. This technology emerged in response to the demands of professional musicians seeking greater reliability and performance consistency. Their presence often indicates a higher-end instrument designed for demanding players.
