Well, I'm happy to report that I like what it did to the mic. YEs, I labelled it so you can't miss it. Will I use it on everything? Nah, but for snare drum through my api pre it was WAY better than a stock 57 plus I had fun doing the mod.
If you think it's a stupid idea then don't do it..
If you like to tinker and have plenty of 57's then try it..
it really doesn't matter
