I did some mic tests yesterday, with and without the sound blanket hanging behind and then adding another sound blanket over the top of me.
The blanket behind did make a noticeable improvement, but the best results were with a blanket behind and a blanket over the top.
When I first got them, I found that folding the blankets in half makes noticeable difference, so that is how I've used them here.
If Dave had folded his in half, he may have gotten better results, but that depends on the blankets. I got mine from
http://www.Marketek.com for $20.00

I bought some blankets from a moving box store, but they weren't nearly as effective. The Markertek blankets were larger and of a much higher quality.
I'll probably get one more blanket so the sides of the makeshift booth are covered at least half way.
This is more about cutting down the volume escaping than mic isolation. I live in an apartment and need the booth so I don't disturb my neighbors if I 'need' to cut tracks at100:PM or 2:00AM.

I'll posts pictures once the makeshift vocal booth is finished.
I also went to Samash and bought a couple of mics to to try out.
- Studio Projects B1
- Audio-Technica AT2020
I had planned to buy an MXL V67g, but the sales person let me do some quick tests at the store and it got eliminated there.
It sounded good, I just preferred the other 2 since the V67g sounded too similar to my MXL 1006.
I did some basic testing at home yesterday with the two new ones as well as the 1006 and the problematic AKG Perception 100.
Right now, the Studio Projects B1 is the favorite, not by a landslide, just prefer the slight difference it has, plus the extra features and the included shock mount.
The AT2020, sounded good and I'd probably be happy with it if it was the only mic I had, but side-by-side with the B1, the B1's quality seems a bit better.
The surprising thing though, was that the AKG sounded so much better with vox booth set up than it had previously, even better than in the 'hallway booth' (TM).
I had been getting these huge spikes in volume plaguing some notes in my vocals recordings and making it difficult to get a good take.
The vox booth set up seems to have eliminated or tamed them way down. I very surprised by this, but it makes sense if you think about it.
It was the reason I switched I finally switched back to the MXL. The Perception 100 is a good mic for the money, but I prefer the others at this point.
I also bought some Auralex MoPads. While they did make a difference, I think most of it may be due to the fact that the monitors are now angled downward and weren't before.
I will say that they did cut down the vibration I could feel on my desk when I touched it.
I bought one of the Auralex room kits yesterday. I will update when I get that in place.
