A guy on another forum, is looking to buy a cheap clip-on condenser mic for his acoustic guitar. Aside from the mounting issues, the mic has an unbalanced 1/4" TS phone plug, and is listed as a 1kOhm mic. He says he wants to plug it into "a mixer". What specifically are the issues here? How does he use the mic properly (if at all)? Oddly, his alternative mic was a much more expensive Audio-Technica AT831b ($300.).
