Psychedelic" sound born in the chaotic world situation of the late 1960s. There is one and only modulation effect born in Japan that supported the tone.
A sound that twists and swells. The heavy tone rotates and sways like cutting the wind. The tone of the mysterious box, whose name was almost unknown at the time, further deified the sound of the left-handed guitarist who is still said to be "God."
Uni Vibe. That equipment was so called. Artists around the world are still looking for original models.
The Animals Pedal Car Crush Chorus / Vibe is a chorus / vibrato pedal that makes such vintage modulation sounds simple.
