Finally, After many doubts that I had about this pedal I went to music store in Montréal (Boutique Tone) and try another one(T-rex replica delay). The way this pedal behave is strange. When you turn the delay volume knob (top left one)as you increase the echo the volume of guitar goes down. On top of it, as you turn the echo far right the mix is more wet than dry. So before you buy it, try it. Sure the echo is nice, I'm thinking seriously of getting back my Re-501. Tape echo is the way to go, in my opinion. I will try a few more delays(maxon,diamond) but my mind is pretty made up.
