Ok I recently purchased the Boss ME-50 and im pretty new to guitar pedals but whenever i turn it on and try to tune with the pedal or do anything i can't bc the number "6" blinks in the display. Right when it turns on it starts blinking off and on and i dont know if thats how its supposed to be or not but its really anoying when im trying to tune or go through stuff with it and all i get is a blinking 6.
