first off, can you use the lm-2 as a basic equalizer using the tone control? how does this parameter affect the sound exactly?
secondly, is there any way to get just reversed sound (no dry signal) from the dd-6? i know the stereo outs do this on the delay setings but does it work with the reverse?
yup you sure can but its not quite the same as a full fledged EQ because it cant cut or boost as much as a straight up EQ. if youre in a pinch you can use it like this but i recommend using a graphic EQ as most people find parametrics harder to dial in their sound.
