I have a Super neo 29" that's practically new, so I don't know that it's something physically wrong with my cab, but my question is if there is different wiring within these MVS cabs that is different than a regular jamma cab in regards to audio? I have tried a number of pcb's with varying results with the audio- some work, and some don't. But one I have zero problems with sound is Darksofts MVS multi- works perfectly. What am I missing, or is there something I could/should do to get proper audio in this cab? As a note, I am not talking about pcb's that require -5 for the audio. Thanks for any help-
