hi katy, may you ask john what bass he played on Mtv Unplugged? Many thanks, Marco

"Hello Marco..It is a Yamaha Fretless acoustic bass APX-B12F.. I thought it was the most beautiful acoustic bass of that period. I bought two and added frets to one- I imagine that is the one I use on 'Unplugged'. It is currently on show at the Rock + Roll Hall of Fame. JT"
