Word of the music legend's passing caused searches on the Web to immediately hit a high note.
The 1960s sound was not about precision, Marshall said in an interview with the Associated Press in 2000. The sound he wanted was "raw, fuzzy power." The kind of ear-splitting sound that can be heard in an amphitheater above the roar of the crowd. That kind of rough, raw sound is what the Marshall amp could bring, and it's what rockers wanted.
The website for his company, Marshall Amplification, posted a message that read in part: "Your memory; the music and joy your amps have brought to countless millions for the past five decades … will always live on." Marshall was 88. He is survived by two children, two stepchildren, grandchildren, and great-grandchildren.
