I came across this article thee other day, and thought I’d share it. One thing I found interesting about it, was how some big names got their signature sound by having crap gear 
Just goes to show you…
One of my favorites was Geezer Butler
“So many people ask me how I got the bass tone on the first [Black Sabbath] record,” Geezer said in his July 2004 Bass Player cover story.
“It was by accident! I had a 70-watt Laney guitar amp and a Park 4x12 cabinet with only three speakers in it—and two of them were wrecked, That’s how I got that really distorted sound.
“At times I’ve hated my sound, and I’ve tried to dial in whatever sounded modern at the time. It never worked. I remember trying to sound like Chris Squire [of Yes]. Ozzy’s reaction was, ‘What the hell is that?’ I was attempting to get a sound I liked to listen to, but it didn’t fit my playing style.”
