Hi!
Just bought a moogerfooger midi murf. No included power supply. Its not working like it should. I´m assuming the reason it is not really doing anything with the sound (running guitar through it), is because my power supply is not the right one?
It lights up, it lets my guitar run through it, I can control the gain etc. Just that the filters don´t do anything…
Cheers!
Yes, it was the power supply (to answer my own question). So if anyone experiences similar behavior: the unit “working”, but not the filters - make sure you have the correct power supply. 
Cheers!
