Williams earned a degree in music composition and theory from New York University, where she took an interest in styles from math rock to Ethiopian jazz.
Then we have the Audio Sprockets Tone Dexter that allows her to map her recorded guitar tone and blend that with her soundboard pickup almost giving her acoustic a 3-D sound.
For someone who gave up electric guitar for its tonal limitations, Williams is definitely becoming a pedal junkie.
It is a solo guitar, so the tone has to be on point.
