But kidding aside, i like all dominant chords on the A position. With funk, simple changes between the dominant forms of the same chord (ex, changing between D6, D7, D9, D11, Dsus2, Dsus4 etc), combined with rhythmic muting can create some interesting grooves. Then play some myxolydian single notes over any dominant chord, and you already have a funky tune. Versatile, yet very easy once one learns the concept.
