When you see a dom7, add a II in front of it: F7 becomes Cmin7 F7, Bb7 becomes Fmin7 Bb7, etc. You'll hear throughout this solo that I've used that sound on each dom7. You'll also hear that I've created II V's off of the "sub V7" to create a more "outside" sound. You can hear all the great jazz improvisers make use of both of these sounds on a blues.
