Please bench test the rod prior to installing in your neck. We check all before packaging to ship but its a good ideal to double check the function yourself before installing. Issues are very few.   Test the rod by placing each end of the rod in a vise and moving the rod in a normal  motion and  check the rod function. After you install the rod can be difficult to remove/repair.

Warranty: Warranty only covers refund or replacement.  DWS Guitars is not responsible for repair or replacement of any guitar or neck due to installation or product failure.  modifications void rod warranty. Please contact us with any issues.
