Thanks for your fast reply.
Actually, I thought the HX One is capable of being relocated with the 4-Cable-Method (just like the Möbius or the Synesthesia by GFI).
I would have thought that I can plug my drives into the loop of the HX One and decide per preset if I want it to come before or after the drive section in order to use it as a wah before drives or a reverb after drives depending on the settings of the preset.
Regarding the last part: no, I don't hear them at all.
