I'm still using my GT-1K, and really like it, but I only use one preset for with 2 channels and some basic effects for everything at church. I have a few presets set up similarly but with different models that I use for my stuff, just doesn't seem like I'm maximizing what it can do. So, I have a RK5 v2, AMT P2, and AMT B2 laying around, along with some various other pedals and a 2 channel DI box, so I bought a b-stock Rockboard to see what I can put together. And yes, have to dial back the gain on any of them or just use my modded SD-1 for church use. Not sure if it will replace the GT or not, I keep flipping on that. But, never bad to have a backup of some kind around I guess. The Rotary effect on the RK5 is pretty cool, may use set it for that and run external delay and verb pedals, I have a TC HoF and Flashback, then can feed the DI box in stereo.
