I'm not having the volume issue in my amp's loop. I think there may be some limiting on the wet signal maybe that makes it seem quieter if you feed it a high impedance signal from something like a guitar.
Worth noting that there is limited explanation of how the modes work in the included documentation so it takes a lot of experimenting to figure out what is happening. I can def say guitar isn't the ideal tool for this but I expect there will be more information soon. Basically, all the big controls have a detent but some of them work smoothly through their full range and others do different things as you go either direction from noon. Im currently finding the Red Panda Particle II to be more intuitive for similar sounds in a lot of ways but Cloudy does more "things" if you only have room for one weird box.
