For Sale... Kala Ubass Fretless Mahogany. I bought on a whim after I saw one in concert. Shortly after I switched to only 5ers and have not picked this up since. I have had it about a year. It is in Mint condition. Comes with a Uke Crazy case. It has the original strings on it but they have only been played less than ten times. PM me with any questions or if you would like to see more pics.
