4 Pcs Black Violin Fine Tuners For 3/4-4/4 Sturdy String Adjusters Practical Replacement Accessories

Micro Adjustment Rotation Structure:The small threaded rotary core delivers tiny incremental shifts to string tension, letting users tweak tone levels in small increments without large jumps in pitch during daily practice and performance Universal Tailpiece Mount Layout:The unified outer fitting outline aligns neatly with the reserved mounting openings on standard sized instrument tailpieces, forming a steady attached joint without scratching the original instrument surface Plated Solid Metal Frame Form:Integrated dense metal body with uniform outer coating holds steady rotational smoothness through long term frequent twisting movements, maintaining consistent turning feel over extended use cycles Smooth Threaded Operating Profile:Precision cut inner screw threads rotate freely without catching or slipping mid-adjustment, holding steady tension values once tuned to the desired tone level General Violin Fine Tuner Fitting Guidance:Loosen instrument string tension slightly before mounting the adjuster onto the tailpiece opening, align the threaded rotary section to the string anchor and turn gently to adjust tension; store spare adjusters in dry closed space when not fitted to the instrument
