I don't see why you wouldn't own one of this. Sounds awesome, cost less than a dedicated analog pedal, and you have a full rig in a box, with looper and drum machine. AND you can load NAM captures. AND runs on batteries. The only gripe is like other users have mentioned, from the pedal interface one cannot select other drumkit than metronome, but I'm assuming this will be easily fixable with an update.
I have not tried the looper so I can't comment on that.
I was on the edge of buying the GP-5 just before this one got announced but I was concerned about depending yet another companion app, but I gotta say that the GP-50 has a well designed UI and everything is easily accessible from the onboard controls. Even if you use it as full rig on a box or multi-effect in the fx loop of an amp. Really good piece of gear.
I am assuming that the best complement for this little guy would be a Hotone Ampero II Press and a M-vave Chocolate so you can get expression pedal and extra footswitches and you still get a full rig for little less than 250 e, which seems crazy to me.
To chime on the sound quality, I have built a patch to mimic what I have with my SLO-mini and NeuralDSP SLO X, the controls are not exactly 1to1 but in the same ballpark and it sounds just as good! It's great to have options and this option is awesome!
