That way the heads 'in front' of the feedback head then added echo to the delayed feedback signal again, along with the incoming signal from the input. In the two pedal method only the virtual head(s) in the second pedal would add echo to the signal from the feedback head(s).
Depending on the level of the feedback signal I suppose the difference might be subtle?
I can't pretend to be able to understand all of that Phil, but what I do know is that what I have done by setting these two pedals up this way the sound equals, if not betters the competition. Whether it's technically right or not matters little when compared A/B against the H&C and Strymon Volante on the same intended settings, as the two £40 machines sound identical to those mentioned. As I said, a single NUX Tape Core pedal will produce the Apache echo when the head values are tweaked with the computer and a good Echomatic 2 pattern is available by using a pair.
