**Nano Cortex + Send/Return GT-1000 or HX**

Is anyone else having difficulty ( tone suck ) using the Nano Cortex in the send/return loop of these units?

I saw a video on YouTube where people mentioned some challenges with this setup. Does anyone here use it this way and could share their impressions? :alien:

Hi, I tried to use my nano cortex in the effects loop of my HX One to choose pre or post, but I had a very noisy feedback when effect was on. Does anyone has the same issue ?
