Flamma FC05 Multi Modulation

On my main board I don't really need a lot of effects, but now and then iIlike to use a little chorus, flange etc. And that's why I bought this pedal. it's very affordable, is small (wich ofcourse makes tweaking a little difficult) and the effects are good enough for me.
One strange thing.: when I put power on the board all the pedals work fine, but I have to take the power cable out of this pedal and plug it in again before I can use it. I have this pedal in de loop of my amp, together with three other pedals and fortunately everything else on my boards works fine, even if I don't "activate" this pedal.
