i am restoring an old king mortone. Originally this bass has a Eb neck and longer string length. I have been unable to find a king neck to replace the "homemade" one someone put on there so I will be putting on an Englehardt neck with will be a D neck and 41 1/2 string length.......I had ask on the "wanting to buy" forum and someone said that changing the string length due to changing necks would cause a problem. I do not see how it could but wanted to ask everyone what they thought????
