I`m making an electric cello, but I have no experience with cellos ( I know, smart idea... ). I`ve been able to get measurements online for most of the parts, but one thing has constantly eluded me. The length of an unused cello string ( IE, straight out of the package ). I need to know this so I don`t make the bridge/tailpeice/etc. incorrectly.

Thank you for reading/replying!
