Could anyone recommend a good self-powered floor monitor? I'm going to be using it in my house so I can plug a mic in and hear my vocals over my guitar in a way that would be closer to a live environment. I don't want to get into the whole PA system thing. Been there. Too much gear for my application. I find that when I'm playing my guitar at moderate volume, I have to force my vocals out in order to make them audible, which changes the tonality of my voice. I'm just looking to be able to sing normally and still hear it over a semi-loud guitar. It would also be a huge bonus if the monitor could act as a decent keyboard amp as well. I don't need any fancy controls, but I would like a quality product. Looking to spend $350 or less, but would be willing to go over for the right product. Thanks in advance!
