Ever since its introduction, the Analog Man King of Tone has been one of the most sought-after overdrive pedals on the market, so much so that if you want a new one you have to get on a waiting list – which, by some current estimates, is about five years long! 

The King of Tone is a double-channel pedal based on heavily modded circuitry from the Marshall Bluesbreaker pedal, each channel having internal DIP switches for a choice of Overdrive, Clean and Distortion modes.
