By the end of the week I will have three tenor ukes in the house. A flea a fluke and A kelii. My question is I would like to turn one of them into my low g uke. I am thinking the Flea. What is the diameter of a low g string and would I have to do any work on the nut? I would like to stay away from a wound string. Is this possible? Any comments are appreciated. Thanks very much.
