Thanks for the answer .... first of all I think I have explained my post wrong ... I totally agree with everything you say, and all you say I also do ... All I want is to explore more alternatives and use a pedal that will be fixed in the effects chain before delays and reverbs. The pedal in question that I want to, is a clone of the preamp section of known korg sd3000. And all I want is to make the connection of the pedal, the way I'm asking, and I want to see the difference this can affect the sound and tone, and finally see the result and choose what best listen to my ears. I use the 4 cable method and L6 link at the same time, and yes I hear differences ... maybe other users are in agreement, I accept all criticism and I'm on this forum to learn from all your experiences, because the point of all this is to improve and find the best performance of our gears. So, I want to connect my pedal with my HD500 and use it with my DT25 FXLoop, and my question is how to make the connections.
