Solo
I find it easiest just to improvise using G Blues. There are four scales you can use to do this:
e|-------------------3-6|---------------------6-8-9|
B|----------------3-6---|------------------6-8-----|
G|-----------3-5-6------|-------------5-6-7--------|
D|--------3-5-----------|----------5-8-------------|
A|---3-4-5--------------|-----4-5-8----------------|
E|3-6-------------------|3-6-8---------------------|

e|-------------------------------15-18|
B|--------------------------15-18-----|
G|------------------15-17-18----------|
D|-------------15-17------------------|
A|-----15-16-17-----------------------|
E|15-18-------------------------------|

e|----------------------------------18-20-21|
B|-----------------------------18-20--------|
G|---------------------17-18-19-------------|
D|----------------17-20---------------------|
