When Robbins was recording his 1961 hit "Don't Worry" at the Quonset Hut Studio in Nashville, session guitarist Grady Martin accidentally created the electric guitar "fuzz" effect – his six-string bass was run through a faulty channel in the studio's mixing console. Robbins decided to keep it in the final version. The song reached No. 1 on the country chart, and No. 3 on the pop chart.Joel Whitburn's Top Country Singles 1944–2001
