Our collapsible guitars use bridge pins to hold the strings in place. The strings need to exit the pin holes in a straight line over the saddle so that your string spacing is even. If you have a string (or multiple strings) exiting at an angle, then the spacing of your strings will be uneven. To resolve uneven string spacing, simply twist your bridge pins and re-allign your strings so that they exit the pin hole evenly over the saddle. In the pictures below, you see the "B-String" exiting at an angle in picture on the right with the red circle, making the string spacing uneven between the 3 higher strings. The picture on the left shows the strings properly exiting the bridge pin holes for even string spacing.
