Ok, so my setup right now for recording guitar is as follows; -Behringer C-4 Condenser mic -Shure Sm57 -Behringer Europower PMH880S Rack Soundboard -M-Audio 410 Firewire (I know my setup is terrible) I'm having some weird problems with popping and hissing, it's definitely not clipping. I've made sure of that much at least. Also I've tried Switching the cables, & the mics. Which leaves the M-audio... Has anyone else run into this sorta problem before & if so what did you do about it? Thanks in advance.
