bassman314, sounds like you have a tight tollerance for your 'B' length.. Strings can vary +/- 1/4" in the making.
Baron, 39" Scale length.. Wow, sounds like you have your work cut out for you. Playing horizontal with EB I prefer just 34". That feels about the same as 41-42" upright with a Double Bass for me... Sry, but we do not have any plans in the near future to make strings of that length.. Thx anyway for asking....
Juneau, if you split the difference between the Nut and the post you will get 40".. If the string is too short, it wont work. Too long is less of a problem unless they break on the Post..
zero7, sounds like you have the situation under control..... Thx for the plug..lol
Great work guys, thx and keep 'em coming..
