From the post
Here's another one from Marshall's great pedal line from the early 90s. When it was released it was considered a high gain distortion, though probably wouldn't be categorized as such today. It was made famous by Thom Yorke and Jonny Greenwood from Radiohead and covers more than just shredder territory.
