I have noticed that there exists a small delay in several presets on the H-8000FW before the actual effect kicks in. I.e. in #524 (I think it's ping-pong delays – I am not sure because I am not in front of my H-8000FW) there is such a small delay. Are these presets meant to work in parallel with the dry signal? I mean this is the only way it makes sense: the dry signal with no delay (hopefully) and then the wet signal with the delay.
I suppose it's just a simple case of adding a mixer in the VSig to modify the preset, right?
