For the price of a headrush gig board, you could get an Atomic AA6 and a focusrite or presonus interface that will both sound better than the headrush, and support microphones for vocals and acoustics. A used AA3 will save you a few hundred bucks. Does the iridium have XLR outs? That could be an affordable option as well.
The podGo could work but the balanced outs are TRS so you would need an adapter or TRS to XLR cables. Obviously the bigger Helix, plus Kemper and Fractal stuff will work if you want to spend more.
The headrush are now Stone Age modeling, and are not worth the money. If you want 11R modeling, get a used 11R for a fraction of the price.
