Specifications ■ Guitar effect pedal ■ Tremolo ■ Controls: Speed, Duty ■ Dimensions, Weight: 82(W) x 110(D) x 44(H) mm, 350g ～From the manufacturer's website～ ■ The D-Spider makes it possible to output a powerfully unique sound that has never been heard before. Unlike conventional tremolo units that control the volume "high and low," this is a unique item that controls the "presence or absence" of output sound, like a switching technique. The timing can be set from a very long cycle to an extremely short cycle. In addition, the input sound source is not limited to guitars and basses, but can also be connected to keyboards, vocals, MTRs, and track-downed sound sources such as CDs, allowing for "DJ effect"-like applications. Furthermore, it is equipped with an extra output, so it is possible to use two amplifiers to pan the intermittent sound left and right, one note at a time.
