The preamp in my interface just isn't doing it for me. I'd like to find a pretty simple tube mic pre schematic. I mean really simple. A tube and a gain knob is really all I need. I just don't know how to build one. If anyone knows where to get the schematic for a Blue Robbie preamp that would be awesome. Been wanting one for a couple years now. Thanks for anyone's help!
