I've tried other voice amps, and none of them compare to the sound quality of the black
Radio Shack amps. They are a bit large, but most of the bulk is in the casing. Once you
break it apart, it isn't that hard to distribute the smaller components as you see fit.
As for me, I'm still debating whether or not to put the speaker in the helmet. It seems
like the most logical place for your voice to come from, but shielding against feedback
has been a challenge so far. Any suggestions from the veterans out there?
