ToadWorks Death Rattle is a Professional Series effect pedal consisting of two channels of overdrive, as well as an independently switchable boost. Each channel has been precisely designed to emulate classic tube amps sounds: the Tweed channel does a dead-on impression of an early era American tube amp, and the Plexi side delivers high-gain crunch of the classic British amplifiers.
