There are legendary pedals, and then there's the Tube Screamer. Introduced to the public with the TS-808 Overdrive Pro, the midrange scream and sonic dominance of this unassuming green box immediately established it as a defining figure in the effect world. The TS-9 continued its predecessors legacy and was made a coveted effect after being popularized by Stevie Ray Vaughan. In the nearly 40 years since the original's debut, the Tube Screamer has seen plenty of permutations like the TS9DX, TS-10 Classic, and Tube Screamer Mini. Whatever your style or genre, any one of these variations on the overlord of overdrives is worthy of consideration.
