VAULT EA20LHNT Acoustic Guitar Basswood Tech Wood Left Hand Orientation  (Beige)

Vault EA-20 comes with a dual action truss rod which gives you the liberty to adjust the action of your neck in either direction if warped. This is a more advanced design and is used by modern luthiers over the vintage single truss rod. Thus, a warp in the neck in either direction can be fixed. This extends your guitars life by making it more resilient to climate changes. Guitars without this dual action truss rod need hefty repair jobs to fix neck warps.
