this is really a trick question, YES it "works"
but not as a stand alone unit
we do not know if he is recording into a laptop or not
so to clearify for him
YES the coax works on a stock unit if plugged into a pc
NO it doesn't qwork if plugged into a Microtrack UNLESS it has a digi mod
so untill you know 100% what you want to use as a recorder, you may or may not need the digimod
