I've been intrigued by May electronics internal microphone system and have devised my own makeshift internal microphones for my toms for some upcoming recording. Right now, i've got small-diaphragm cardioid mics in each tom with the element about 1 1/2" from the head. My bassist, who is an aspiring self taught engineer is being a total stick in the mud about the whole situation saying that they will never work and sound like "a tin can" which i always retort that he's only ever recorded 1 band so he doesn't have the expertise or experience to have come up with such an opinion. His take is that we can't position the mic when it's in the drum, my take is that with the mics being internal, there's really less of a need to get positioning perfect. I won't have to worry about crosstalk, room ambience or frequency cancellation when the mics are inside the drum and i can create some incredible sounding stereo pan effects that would be impossible to do with standard external mics. Truthfully, i don't know either, i've never recorded with internals, save for the bass drum. Does anyone with actual experience have any opinions?
