Marshall JCM800

"With the newly introduced Master Volume feature, the JCM800 allowed for crunchy, sizzling distortion at low output levels, making it the amplifier of choice for heaps of hard rock and metal players, including Slayer’s Kerry King and Jeff Hanneman and Slash of Guns N’ Roses."

"Sure, we can discuss which amp was the biggest gamechanger. But just imagine hearing this amp paired with a Tube Screamer back in the early 1980s. The tone was unlike anything ever heard at the time. The original variants featured only one channel. But being a specially designed tube-driven amp, JCM800 entered some super-heavy territories when paired with appropriate overdrive pedals."
