Db7#5 is the Db augmented seventh chord: Db, F, A and Cb, built as root, major third, raised fifth and minor seventh. The augmented seventh chord adds a minor seventh to an augmented triad, so it keeps a dominant function while raising the fifth. The listed voicings run from fret 2 up to fret 10.
Its enharmonic twin is C#7#5, which sounds exactly the same. Notes such as Cb are written that way to keep one letter name per chord tone, even though they sound like simpler notes. The chord tones all belong to the Db whole-tone scale, a good starting scale when you improvise over this chord. Switch on the microphone in the interactive fretboard at the top, play the chord and see which strings ring.
Db dominant 7th with sharp 5th guitar chord is also written as Db7(#5), Db7#5, Db7+5 or Dbaug7.
