Shure's PG81-XLR is an ideal condenser microphone for acoustic instruments due to it's flat frequency response and consistent sensitivity.
PG Microphones are the pro-quality, versatile
introduction to Shure engineering excellence,
featuring cardioid polar patterns that reduce
background noise and feedback. With a lineup
that includes XLR and USB side-address
condenser models, PG microphones are built
to withstand the demands of everyday use,
while delivering pro-caliber sound that’s ideal
for rehearsal, performance and recording.
