This was my dad’s PA setup when he was touring in the 70’s-80’s and then was gifted to me when I became a teenager and had a band and needed a PA to rehearse in my mom’s basement. In fact he still owns and uses the speakers for his rehearsals with his bands to this day." - Frank

John Fogerty recalls the song started to develop during a quick soundcheck at the Avalon Ballroom in San Francisco about spring 1968: "I plugged in to my amp and I started hearing an E7th chord with that swampy vibrato that I was making on my little Kustom amp. It just turned me on to be standing there – I was so excited that I was playing in front of a real audience in San Francisco; I was just charged; and suddenly, I was inspired. I turned to the band and said “just start playing E”, and I started screaming at the top of my range, just a melody and vowel sounds and consonants. --- Then suddenly, right in the middle of having this burst of inspiration, it went silent. The stage manager had pulled the plug out of my amplifier. I looked at him and said, “Why’d you do that?”, and he said, “Don’t worry about that, you’re not going anywhere anyhow.” --- I looked at him and said, “Not going anywhere? You give me a year, pal, and I’ll show ya who’s not goin’ somewhere!”" (John Fogerty on his official site in 1997).

In a live performance image found on Pinterest, Matt Parrillo, also known as Mauz, is seen using the Kustom K200A-4 amplifier alongside his Ibanez Iceman and a Laney cabinet, likely at Gilman Street. Additionally, in a Reddit post, Dino Sommese from Dystopia mentions that Mauz employed two amps slaved together during the recording of their self-titled album: a Sunn Model T and an unknown Kustom amp. Although Mauz owned two or more Kustom amplifiers, this particular Kustom model was frequently used during the later days of Dystopia.
