Hello! I have just purchased this kit from a shop here in Norway.
Yesterday,i assembled the kit ,and tested it on my sound-sytem, when i activate the Vocal reduction the sound becomes very strange, as if you put a loudspeaker element into a tube, i have checked and re-checked that all the components are correct and soldered into the correct positions.
I cant find anything wrong, can anyone please advise me what to doo??
