Hi. I am currently running a bass rig where I use two different heads for one cabinet. ( one for the high's/other for the lows). I am running no effects through the low end but several through the high end as they cut through better obviously. Where my problem comes in is here. I am using a Morley ABY switch to run both heads simultaneously......and when I plug the wireless in all I get is the low end. When you use a regular cable they both work. I contacted shure about the issue and they are scratching their heads. Can anyone help me fix this mess? Thanks!
