Vocals - rehearsal

I just use a 58 into a not so great p.a. Pushing about 300 watts a side, tops no bins. Depends what I have lying around, sometimes I link up extra speakers to get a bit more out of the amp. Recently got rid of my 16 channel studiomaster desk for a tiny thomann brand thing with 4 mic ins since the big desk was complete overkill and took up space. Does the job, can usually hear the vocals pretty well. I'd love to get a more powerful poweramp and a 2 channel comp to run the outs through. a set of bins would be great too then I'd mic the kick. As it is the kick eats too much headroom and when you eq out the lows and boost the highs and mids it sounds very strange and doesn't help much.

What I've done a few times is run everything through my firepod and sending the feed via a line out post processing to the p.a, worked great. Was able to eq the low, compress it and add in a little verb and delay to sweeten it up. Could hear vocals alot clearer with this set up but I've to carry my rig to practise and takes a while to set it up. Also needs a good bit of room which I don't have with 5 guys and all the other gear already in the room.

Sometimes I run the control room out of the desk into a bass amp I've got too for a extra volume. It's great cause there's a huge volume increase and by playing with the bass amp volume and eq and the control room outs volume on the desk I can get a nice clean, loud feedback free boost for the vocal. The bass amp is a complete piece of crap but does this job very well.
 
I was mostly thinking of PA options. There's are so many things made for guitarists (and threads about them) but very few when it comes to vocals. Well at least things that would seem to be specialized in this area. I have a DAP Palladium 700 amp, some shitty speakers (now I know) and constant problems with feedback.
