Radius Mandolin™ PickupThe Radius mandolin pickup is a hi-tech contact sensor that was designed to emulate the sound of a mic Without the instability associated With microphones. The pickup installs easily to the instrument With mounting putty that is non-destructive to its finish. Inside of the pickup’s housing is a highly flexible film sensor that responds much like a mic diaphragm. The sensor is held in equilibrium and damped by opposing neodymium magnets that allow the pickup to respond to the instruments most subtle nuances.FEATURES: Radius pickup Mounting putty Clear adhesive pads Permanent VHB pads External jack mount Radius Mandolin™ Pickup GuidesRadius Mandolin Pickup Installation Manual & User GuidePLEASE NOTE:LR Baggs products must be installed by an authorized LR Baggs dealer to qualify for warranty coverage.
