Donner Morpher effector with True Bypass function. A clone of the SUHR Riot. Rumor has it that it's the same as the MOOER Solo (around 7000 yen) (^_^)b Get good sound at a low price. A surprising point is its good responsiveness to the guitar's volume. When you lower the guitar's volume, it goes from crunch to a cleaner sound. Cheap distortions tend to only decrease in volume while remaining distorted, but this model properly reduces the amount of distortion. Only used indoors. Selling because I no longer have any live performances planned.
