A Screamer pedal, often referred to as a Tube Screamer, is a type of overdrive pedal known for its ability to add warmth, mid-range boost, and a smooth, bluesy distortion. The most iconic of these is the Ibanez Tube Screamer, which has become a staple for guitarists seeking that classic overdrive sound. The “screamer” effect is typically characterised by its ability to push an amp into natural distortion while maintaining clarity and articulation, making it a favourite for everything from rock and blues to metal.

Screamer pedals generally offer mild to medium overdrive with a prominent mid-range emphasis that cuts through a mix. This makes them popular for solos or when a musician wants to boost their tone without overwhelming the natural sound of their instrument. Various versions, like the Maxon OD-808 and JHS Bonsai, have expanded on the original design, offering more tonal flexibility and options for modern players while still keeping the core “screamer” character intact.
