Topic: Well...... I tried it.
I've got a Seymour Duncan Woody pickup on my guitar and using a dynamic mic for my voice (Samson Q6), both put through the two channel amp, and then a USB mic (Samson CO1U or some such) in front of the amp to record the output. It worked ... OK. Not great. I like not having to sing loudly and being able to mix, but it sounds a bit like I'm doing the recording in a sewer. Next attempt (who knows when) will be to record through my sound board with USB output to the computer. I'll see whether my acoustic amp will double as a monitor, or maybe the sound board has headphone output. It's all an experiment. Wish me luck.
Maybe some day I'll get this well enough to take care of the couple of collaboration projects I have from Geoaguiar. I think he's only waited a year or so. I owe that man a beer (or treat of his choice) should we ever meet just for his patience.
