I'm planning to build an EUB, 1051 mm scale (3/4). I want to make the overall bass as short as possible, with compact headstock and no tailpiece (eg Azola). However there's a lot of extra wound string length, forcing me to keep a long headstock if I don't want the metal wrap to go around the tuners. I've thought of using 1/2 size strings on my 3/4 scale instrument to avoid the extra length. So I have two questions: - Do you know if there's a standard wound length for strings (eg, from ball end to start of cotton wrap)? - Are 1/2 size strings different from 3/4 in any way other than length?
