I'm looking for a microphone that has a somewhat 'telephonic' sound. Lo-fi, even naturally overdriven sounding. It would be used for an 'effected' vocal sound... peppered into the songs as opposed to being the staple vocal tone. I've tried pre's and EQ's... and they are not bad, but i've really wanted to go a little more minimal with this project, and find a microphone that has this certain tone to start with. Frankly i'm a little lost now. Megaphones are too honky, harmonica mics (at least the one i've tried) is still a bit too clear and normal. Does anyone have any suggestions? I've heard of the 'coppertone' mic that has similar traits, anyone have any experience with them? thanks!
