FROM FUNNY LITTLE BOXES:

The Skeleton Key is FLB's love letter to the unique guitar tones found across the back catalogue of legendary desert rockers Queens Of The Stone Age. With extremely interactive Gain, Tone and Volume controls, which when combined with a down tuned guitar push your amp into growly, scratchy, thunderous new frontiers.
