yea i checked these dimmers before i installed them to make sure they were buzz free!
A little update..
Today I built the back wall absorber in the booth, and I build the front obsorber which holds the computer monitor. I also put up some foam to see what it would sound like in there, and it really does sound unreal. Rockwool makes a HUGE difference. The sound in there is exactly as I would like the mic to pick it up. Completely dead, with no muffling. Im really happy with it!
I also started building my absorbers; after having an hour of problems with 'No more nails' glue, i decided nails were the best option. Ive never been so angry at a product before, i was fuming!
Il post pictures tomorrow, but for now im going to bed to itch away my rockwool imflamed skin =]
