Watch the Strategy 4: End Well online guitar lesson by Jon Herington from Ear IQ: Soloing Strategies

Any ending is what you leave in the audience's collective ear, whether it's the end of your set, the end of a song, or the end of your solo; it's when they get the silence and the space to really consider what they've been listening to and what they think about it. So, it's critical to take care of business where endings are concerned. This is true, naturally, even when playing a guitar solo in the song.
