John Dwyer

"I ask John to instruct me on how to make a Coachwhips-patented microphone. He tells me that it involves 'two screws; you just put the two wires on the two screws.' 'And then hook it to a normal microphone?” I ask. 'No,' he says, 'you just cut one end of a guitar cable, fray out the wires and put it on there. I’ve gotten better at making them over the years. Now when I make them they last more than one show.' At this point, you might be wondering where this endless supply of telephones comes from. 'Hotel rooms,' John says, 'that’s why every time a place puts us up in a hotel, we’re usually not invited back.'" - https://www.slugmag.com/music-features/whip-it-good-prepare-to-be-dominated-by-the-coachwhips/
