Do you improvise during guitar solos?

[mcnach]

A solo does not have to be improvised, on the contrary, the best ones are well designed and practiced in advance.

Indeed.

I keep the one on the root so everything falls in place.
In the between, when the solo is well established, I usually build shallow counterpoints to underline the melody.
I pay a lot of attention not to draw attention away from the soloist but rather reinforce it. It can be difficult.
