Watch the Mental Justice online guitar lesson by TrueFire from Play Country Guitar 5: Lick Vocabulary
Mental Justice - Lick 18 is a video guitar lesson presented by Jason Loughlin and is sourced from 50 Country Masters Licks You MUST Know.
This is the opening lick of the famous Waylon Jennings tune, called Mental Revenge released in 1966. He definitely had a big hit with it. I don't really feel like Waylon Jennings gets enough credit as a guitar player, he is always playing these simple but very memorable licks. The opening to mental revenge is no different- it's a strong intro melody and stylistically it really helps define a lot of the outlaw country sound. Waylon also made it using the phaser effect on guitar, which became popular later on in the 70s and which became a big part of that sound.
