Roy How far is not cut and dried. I start by backing out the lowest screw about 1/8 of a turn, then move to its neighbors (on both sides if its not the end one). Use this amount in the offending section, gradually tapering off the amount. Test the string response. I do this by dropping the tension of the string a small amount. It should respond immediately. If the pins a tight, you can flag pole the pin and hear the string responding. Bring the test string back to pitch and set the pin. Several quick, firm test blows should not affect pitch. Make sure you set the pin and string. If your test notes fail, back out the screws again in the same manner. The whole process is faster than reading these instructions. Good luck. Let me know how you come out.
