I currently have the p3110. Got it for my slab which it works amazingly. For my double bass i borrow an fdeck and a gage lifeline (hurray to generous friends) to try things out, it sounds pretty good. Cuts well with a drummer and guitar. When I first was trying it out at home it seemed pretty underpowered for 300w. But if you are in audience distance you can still hear it really well. I have yet to try it with a microphone. Also one major reason I got it is size. It's is very compact, tilts, and is not heavy.
