Glenn Snoddy, the studio engineer who was at the controls for the historic Nashville recording session that inadvertently produced the sound that became known as the fuzz tone, died on May 21 at his home in Murfreesboro, Tenn. He was 96.

His death was confirmed by his daughter Dianne Mayo.

Though typically associated with ’60s rock — and maybe most famously with Keith Richards’s fat, buzzing guitar riff on the Rolling Stones’ 1965 hit “(I Can’t Get No) Satisfaction” — the fuzz tone emerged from the studio session that produced the country singer Marty Robbins’s otherwise euphonious 1961 single “Don’t Worry.”

A malfunction in the console through which the playing of the electric bass guitarist Grady Martin was being transmitted caused the original fuzz-tone effect, Mr. Snoddy said in a video made by the National Association of Music Merchants in 2014.

The low, reverberant sound produced by Mr. Martin’s bass on “Don’t Worry,” which reached the country Top 10, was reminiscent of a rumbling car muffler.
