Hey all, am currently looking at both Eden and Nemesis amps to upgrade at the moment. I've got a few questions some users might be able to help me with. 1) On the WT600 and WT800, in between the parametric eq controls are four red leds. what purpose do these serve? I can't work out what they are meant to be indicating. 2) What does the DC on light indicate? IE, how is it different to the mains indicater. cheers!
