Exactly meets my expectations (preamp for my Gibson Hummingbird acoustic guitar equipped with a piezo). Without having had time to use the equipment extensively, the sound quality seems to be there. It is a product well suited for those who want both a quality preamp and classic effects (chorus, reverb, etc.) in the same box, which avoids multiplying pedals and connections, thus ease of use. Also ease of sound adjustments, for example the midrange is not parametric, so less precise, but therefore very easy to adjust. I think I will be satisfied with it for a long time (it also seems sturdy enough to last).

Great sound for a rather compact case.
