The Mooer Soul Shiver has three modulation effects that will really take you on a trip. With a standard swirling chorus, a retro-sounding vibrato that harkens back to the '60s, and a rotary mode that simulates that classic "Leslie" sound, the Soul Shiver will really funk up your sound -- for an impressively low cost, in both money and pedalboard space. The Soul Shiver is perfect for artists that want to get a little psychedelic with their sound.
