Grover 305 Series Mid-Size Rotomatics Machine Heads - Nickel

The 305 Series is made with the same quality as all Rotomatic® models. Slightly larger than the Mini Rotomatics®, the mid-size series features an 18:1 gear ratio for smoother, more precise tuning. This compact machine head is perfect for use on smaller and in-line headstocks.
