So obviously when buying traditional microphones, you can get a wide range of audio quality from them. Is the same true with contact mics or are they all more or less the same?

I’ve made two myself over the last year and the only how-tos I’ve seen have been variations on “solder this stereo wire this way and you’re done”. But is there more that can be done to enhance the fidelity of its audio capture?

Or when buying contact mics rather than building, is it worth it to spend more money on something or is it going to be the same as a dirt cheap piece just prettier?

Thanks, y’all. I don’t know much about microphones at all.

didn’t include power electronics, that’s another kettle of fish
