Malfunction
I know this reverb because I tried it, borrowed from my friend, that is why I give it 5 stars for features and sound.
I love it for its simplicity: 1 knob, 1 switch, works and sounds great (if you are lucky, see below).
However the item I ordered is not working well. when turned on, it seems to work, however the reverb knob does not work properly - when turned all the way left, it has huge amount of wet signal, completely unusable :(
