  			This is my first tab submission, so I'm sorry if it sucks.   
I know that it is not totally correct, but I was hoping  
someone might be able to help correct it.  One of the problems  
is that the solo is played on the mandolin, so I took it down  
an octave to try and duplicate the feel on guitar.   
Any adjustments or advice would be welcomed. 
 
Standard tuning 
b=bend 
/=slide 
h=hammer

OK, so that's what I have.  A couple pretty obvious errors include:   
1.  The section that plays: 
 
-------------------------------------------- 
------------------------------3--3---------- 
----------3--3----------------3--3---------- 
----------3--3---5---3h5----------5--------- 
---3h5-------------------------------------- 
-------------------------------------------- 
 
sounds pretty off to me but I'm not sure what it really is. 
 
2.  Everything after  
 
-------------------5h6-------- 
-----------3h4---------------- 
----2h3----------------------- 
------------------------------ 
------------------------------ 
------------------------------ 
 
sounds a little off to me.  You really notice it listening to the recording.   
At the ending the mandolin plays the second to last note 3 times, not just  
2 as I indicated in my tab.  I just couldn't figure out where I got behind to fix it. 
 
Hope this helps as a starting place.  Post something if you figure out improvements.
