Vaughan, a devotee of Hendrix, used the chord extensively. For example, the main riff of his song "Scuttle Buttin'" uses both the E79 and the B79 as part of a 12-bar blues progression. Johnny Winter referred to it as the "Hold It" chord after the Bill Doggett song. This was also a name used by John Scofield. Notes References Sources Further reading Hanford, John.
