Give up on the Universal strings. Take measurements, call Mapes or favorite string maker...get the string within a week and do it right. You can still tune at the first appointment and come back to install the string. I give them a price including part, shipping and the installation appointment. If you have a ringing damper...I've temporarily installed a flat damper or they can tough it out...
