The VO: 1-A-PF Silver Pop Filter matches your Harlan Hogan Signature microphone perfectly. It clamps directly onto your mic and the sleek wrap-around retro design recalls the glory days of Abbey Road Studios, while it reduces plosives and protects the microphone's gold-sputtered diaphragm. * This pop filter only fits our MXL VO: 1-A Microphone. Similar appearing MXL pop filters do not fit the VO: 1-A .
