I tried Mooer Prime P1 as a replacement for my Cuvave CubeBaby (a chinese 35€ ultra-mini-pedalboard with customizable IRs). No big expectations for the sound, hoping it was usable both for practice at home and for "rough" situation like jam sessions, as I have better units for regular gigs.
The unit is sized more or less like a pack of cigarettes; it sports a sound library, possibility of remote control via the GTRS footswitch, and integration with the smartphone, together with possibility of sending backing tracks and a metronome.
I must say though that despite all the nice features, the sounds are quite horrible and I managed to get only a couple of vaguely usable tones. The Cuvave, despite having a really barebones chainn, is anyway more dynamic under the fingers, thanks also to the possibility to add Custom IRs which is lacking in the Mooer.
