ABSORBENT MICROPHONE SCREEN The guitaRF® helps your amp sound like you really want. The guitaRF acts as an RF (Reflexion Filter®), an isolator but also a dual microphone stand and fine positioning hardware for your favorite large diaphragm condenser mic plus a dynamic or small capsule microphone. All in one piece, with the ability to perfectly align the two capsules to achieve maximum impact and less offset. For years, some of our top FOH customers (live sound for Tom Petty & The Heartbreakers, Black Sabbath, Paramore, My Morning Jacket, and more) have known that putting a reflection filter in front of their amps can help Reduce the sound of the stage that spoils that of your guitar microphones. This is especially true with some of our favorite guitar microphones, such as the VR1 and RNR1 tapes, as they naturally have a figure 8 pattern that leaves them open to whatever else is happening on stage. This not only helps the FOH mix. Using an RF on guitar speakers or drums can make multitrack recordings from a live show much easier to mix. People will no longer need to find their solutions. Now we have the GuitaRF.
