i am nott too good on stealth mics, but i would say you would want either the at mics w/ a battery box at the very least, and maybe one w/ a bass rolloff!!
a step up is phantom power because the voltage is stepped up, this helps the mics in mnay ways, it extends their spl's and their freq response too i believe!
also, they can be powered thru many higher end devices w/ phantom!!
but at mics>battbox w/ rolloff>jb3 will sound just fine for ya for now i bet!
maybe add an ad-20 later on and start doing your digital thing, w/ the optical out from the ad-20 into the optical in to the jb3!
