The compact Vivie/CALLION overdrive pedal is now available. CALLION is a high-end overdrive made for professional use. It is designed by focusing on responsiveness, balance of each range, and separation feeling, the elements required for sound creation. Internal parts include carefully selected condensers and high-precision chip parts that are also used for computers, achieving noiseless, three-dimensional sound. The fact that the manufacturer has uploaded a photo of the internal base shows their absolute confidence in the product.
