I've got my new rig tongether and just now getting to play around with it. I love this rig. Variax500 VDI to HD500x w/ L6link to DT25 combo.
I've been using the "Pre" models along and setting No cab as it seem logical to let the DT25 combo have it's sound on the cab. I noticed the weeked that during a performance I had way too much reverb in the sound. I turn my reverb off on the HD500x but it was still there. Then I noticed I had left the reverb knob up on the DT. So I reached around and zeroed it, problem was solved. But it got me to thinking althought I know the knobs are sync'ed the reverb seemed to have largely be coming from the DT when I had too much. Does this apply to some extent to the DT as well?
I see in the "HD Edit" software you can cofigure the power amp to be what ever you want if you want to tweak the sound way from the original. But I also see you can set the Topology as well. I've been leaving this to "I". Since the HD500x is providing the Pre amp model does setting the toplogy even matter?
