Great idea Hakan. I just tried a similar thing with a piece of clear vinyl drain hose I had. It has a 1 5/8" OD and a 1 1/4" ID that fits perfectly over my sm57. I cut it 2 3/4" long, and when I put it on, I left a 1/4" lip above the top of the mic. Sort of like a bulletizer. This does make a noticable difference playing through my micro cube. Better seal, easier to hold and a noticably "thicker" sound. ---------- You Tube = goshinjk
It is very nice to experiment and analyze the new sound that is produced and compare it to the old one. It's fun! And simple modifications like this one is of course easy to go back to the original if you get tired of it.
I have tried some other stuff that significantly boosted the sound of one of my bullet mics. But I want to fix a little bit more first before I show that ;)
