I had to have a second listen when I saw the comment about the bass because on first listen I did not hear it. The unplugged session has different bass in places - yours sometimes has the octave bass so close to the tone of the lowest guitar string they combine - and when they play a 5th apart, as in the original, it doesn't work as a pedal note because they just sound like two notes played on the guitar. The Clapton version has a very bass light low end on the guitar that lets the acoustic bass fit in. Have you tried slicing the LF off the guitar and revealing the bass. It's close enough to the original that it will work fine - it's just a bit light - so a light bass and a heavy bottom string on the guitar are all that's adjustable.
To be honest, I didn't miss the bass - it's a really nice version.
