Simple but effective packaging. Apparent quality: good Once plugged in, wow ???? it's clean, no hiss, the sound is faithful, clear, in short really good. The adjustment knobs are closed, but better that than the opposite. Big plus: there is an on/off switch on the table, whereas entry-level manufacturers don't even think about it. Nice finish, quality product, I recommend it to everyone. I use it to input a guitar+tube amp line, a guitar+multi-effect line, and a sound line from the PC output to play backing tracks. This way, I can balance my mix between my sound and the accompaniment for a very good result.
