    GOTOH H.A.P.-M.  Combining the ability of Post Height Adjustable and Magnum Lock.  Keeping the current function, locking stability has been improved with the introduction of new smaller string holes on 1st, 2nd and 3rd string posts.  Locking feature gives a machine head that is the perfect choice for flat peg-head guitars equipped with Vibrato.  Height adjustable posts take away the guesswork by allowing you to dial in the exact angle you need for, friction, string pressure/tension and open string sound and sustain.  Ideal for flat style peg heads when string trees need to be eliminated.

    1. Look good; great set of features 5 Star Review

      Posted by on Oct 13, 2017

      Gotoh makes great tuners. These give you a combination of great features in a truly vintage look. I want my guitar to look and sound like it is vintage but I want the best technical features I can get. The locking feature works really well although when removing the strings for a change strings sometimes snag. The locks work automatically as you tighten the string; it unlocks incompletely when you loosen strings. Sometimes you have to hold the tuner and loosen the lock a little more to dislodge strings. For the great look and operation, this is a small problem to me. The adjustable height feature is important to allow elimination of string trees which can cause loss of tuning, especially with tremolo use. I found that only Philadelphia Luthier supply has these in stock.
      5 stars for looking and working great for tuning and string installation. 4 stars for the occasional snag on string removal and expense.
