The F augmented seventh chord (F7#5) combines F, A, C# and Eb, that is the root, major third, raised fifth and minor seventh. All 4 voicings are fretted and none rings an open string; 3 are barre shapes.
The augmented seventh chord adds a minor seventh to an augmented triad, so it keeps a dominant function while raising the fifth. A scale that covers every chord tone is the F whole-tone scale, which is where to start when you improvise. Stripped-down versions of chords like this one are the subject of shell chords.
Strum a shape in front of your microphone and the chord player at the top shows which strings ring and which are muted.
F dominant 7th with sharp 5th guitar chord is also written as F7(#5), F7#5, F7+5 or Faug7.
