Thomann sent me a USED unit instead of brand new sealed, I didn't buy a b-stock and the unit was opened and with even some presets modified and fingerprints all over the screen... that bothered me a bit considering I paid for a new unit. Sound wise I thought this thing would be truly great but i was very wrong , it has some fx that are ok , but in general and to be honest it sounds very plastic and too digital with very noticeable horrible latency and big lack of dynamics, I'm very experienced with multi Fx but even tweaking a lot every sound still sound plastic like it or not, the pitch effects are truly horrible with tons of latency and digital crackling, only distortion sounds sound a bit decent but nothing amazing, is better to use the IR included instead of amps and cabinets cos they sound truly bad and muddy, if someone tells you that this thing sounds like analog pedals or real amps is lying or very confused. As a gigging professional guitarist for more than 40 years and having had tons of multi fx , pedals etc... this one is nothing amazing or good enough for professional situations, for a truly great sound I will still using my analog pedals and amp, this Amper is still a toy for kids in my eyes after hearing how it sounds and how it feels when you play.... however if u are an experienced guitarist you can make it sound good enough, just like you would do with any other device, but don't expect a miracle out of this box I'm telling ya !!! all the best
