Valeton GP-50

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!

First of all, I don’t consider this device as a professional gigging and recording tool. Compared to a Headrush Mx5 it’s obviously weaker but has some advantages that made me purchase it and I’m happy with my choice, totally recommend it everyone on every level! Here is why:
-super portable practice tool. Similar size of a regular Boss pedal, built in battery, looper, Bluetooth, etc… you can practice wherever you want.
-perfect backup. Most of us don’t have two of everything, if my Headrush would go down this thing can save the gig. Won’t be the same but good enough to continue. Probably the audience would not even notice..
-perfect tool for a beginner. Easy to set up, sounds good from out of the box. Very compatible device in its price range.
-effects. For this price it’s hard to beat it. Imagine you need a tremolo or something like that in only one song and a vibrato in another.., here you are, plug it into your chain and problem solved. Not to mention the tuner…

After a few days of having it, this is my first impression. I hope it’s helpful.

This one is super. I originally bought the little brother, GP-5, which is awesome but when this came out I immediately got it. Stereo out, expression, midi, looper, on hardware chain editing and control... These are just a few of the new features. I need to say that I never thought I would use it without plugging it but yes it has a 1450mA battery and I use it all the time. Now we still have small issues like, we cannot use the nam and the cab IR at the same time. Of course, for the price, we don't even need to care as far as I am concerned cause this is not great at the price point but in general. Comparing to some of the big names, it has kind of a scooped, duller mids sound in similar loads. No matter, highly recommend. Not to mention you can get two and get two rig-stereo, automate it via midi and even use it as an interface.

I got this so I can practice in silence while using my pedalboard, and also to use it as a stand-in for other effects (phaser, delay, etc.). It sounds very good, although it doesn't like having distortion or hard overdrives in front of it. I have the VS Audio Royal Flush, and if I have both sides on (stacked overdrives), the GP-50 "farts"—though that might just be my headphones. The Tone Snaps are very good and sound quite "natural," but you can still tell it’s not the real thing (which is okay, considering you're only paying 120 Euro).

Side note: I might replace my Hall of Fame 2 and just use the reverb on the GP-50. The Hall of Fame sounds a little better if you really pay close attention, but while playing, you can't really tell the difference.
