Over our C minor chord, we get a triplet figure of all B♭s, making the chord a C minor 7. This is followed by the use of a passing tone (Ab) to get from the 7th to the 5th. Finally, over the B♭, we have an F (the fifth of the chord), moving to a G (the 13th, another tension).
Jazz amps need to produce an absolutely crystal clear sound. While of course many jazz guitar players use a lot of gain, the most important attribute is that clear tone.
