Ever tried playing a video game to the point where you are no longer conscious about the controller and what buttons you are pushing?
That's the point you want to get to when you are playing solos.
As long as the guitar is a tool you have to "operate" and not an integrated part of your nervous system - you will not experience the soloing freedom you long for.
Luckily you can get there today or at least this week with a little focused practice
