No worries! I realise not much of that made sense....
So, basically, there are three of us in the band, and we all share vocal duties. I'm on guitar and whatever device I use - be it Kemper, Axe FX3, Helix etc. - I have the main outs going to my RedSound cabs behind me to give the sound a 'punch', as they feel similar to a guitar cab. I also have another output going to the mixer (wireless Mackie one) so we can all control our own in ear levels and mixes. However, I do NOT go through the PA.
The bassist also uses cabs, and also has a DI out to the mixer; again, just for in ears.
The drummer just hits things loudly, and only has his vocals and sometimes his bass drum through the mixer.
