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"
