can anyone recommend a good one? i have never experimented with them before and i am kind of behind schedule with my current project... any recommendations would be much appreciated. i realize there are a lot to choose from out there. i basically just need something simple that can handle mic, guitar, line, and effects pedal levels.

pretty much, but it needs to be auto-adjusting. i was hoping it could provide enough gain for a mic or guitar signal too...
