Hey man, I do infact run these mics. That Little Feat show was my first so, its a little rough. I just taped Wilco last night and pulled a kick ass tape IMHO
If you would like, I will B&P if for you, I'll PM you my address if you want it.
Of course these are not the best mics in the world. The most common mic in the $300- is the AKG c1000. I've heard a lot of c1000 tapes, and I think the Superlux are just as good. If your on a budget, go for it. But thats just my opinion.
