For the recording of Six Degrees of Inner Turbulence and Train of Thought, Mike used a kit called the “Siamese Monster”. For Octavarium he used a white kit called the “Albino Monster”.
Mike uses TAMA Starclassic drums, Sabian cymbals, TAMA Iron Cobra pedals and hi-hats, Latin percussion, Remo heads and Pro-Mark 420 custom sticks.
He has a signature snare drum series from Tama called “Melody Master”; named after his daughter. There’s also a Sabian “Max Stax” symbals, which are named after his son.
