In Episode 24 of Anatomy of Tone, I delve into the hidden gem responsible for the iconic "Back in Black" tone of Angus Young and others. The Schaffer Vega Diversity System, originally designed as the first wireless unit for guitarists, evolved into a pivotal tool for tone enhancement. The Schaffer Vega sound remained elusive and shrouded in mystery for many decades. However, thanks to Fil Olivieri's relentless research and collaboration with Ken Schaffer (the original designer), a modern incarnation of the original Schaffer Vega has emerged sans the wireless aspect. We now have at our disposal a pedal version of the Schaffer Vega sound, known as the Solo Dallas Storm, and I'll be embarking on some exciting experiments with it. Additionally, I'll discuss Elaine Gould's invaluable reference book, "Behind Bars," which provides comprehensive insights into music notation.
