The sound is better than expected, really good.
The double stereo channel is a winner. The only product at a normal price that has this. I could use even a third one.
It is a very easy the way to experiment. Just push the channel knobs you need in the instant acces mode.
The buffer is handy (apart button would have been better). Apart boost is handy. The rest is not my thing (ctrl, midi, clock, tap, ...) . Too complex but it does not affect the easy playing.
The product is very good. But it depends on what you want. I use it to maintain a light pedalchain with apart circuits for fuzz, rack unit and loopers next to distortion etc.
Very handy. The rack unit is a pedal without tone loss now, constantly available.
It needs a lot of cables of course. You can acces and combine a lot of cool pedals, much fun for playing. For only recording and getting sounds, this would be overkill. It is for me for live experience and making fast combinations between lots of pedals Thomann made me buy.
