now i know the DD20 has its daisy chain issues.
so im trying to look at owners who find a way around these.
power supply?specifics?
did something to the pedal?
ahh..i get tat too..but then,in my case, i get around the noise by turning on the backlight of the dd20..and the noise is gone.I press the 'tap' and 'tempo' button at the same time and the backlight of the screen turns on and the noise is gone.
