Hey everybody, I am building a concert  scale pot lid reso uke,with a piezo pickup.  My string ends will show thru the tail piece.  So ball end strings may be the ticket.  Can anyone recommend steel wrapped nylon strings that will tune like a uke?  Also, string gauges that will tune like a uke.  I intend to play like a uke but may set it up for slide playing.  All ya'lls thoughts are welcomed.  jh
