SE Electronics guitaRF Reflection Filter for Guitar and Bass

The SE Electronics guitaRF acts as a Reflexion Filter™, an isolator, a double mic stand, and fine-positioning hardware for both your favorite large-diaphragm condenser or ribbon mic AND a dynamic or small-capsule mic. Just one piece of gear serves all of those functions --including the ability to perfectly phase-align the two capsules for maximum impact.

For years, some of our biggest FOH engineer clients (running sound for Tom Petty & The Heartbreakers, Black Sabbath, Paramore, My Morning Jacket, and more) have known that putting a Reflexion Filter in front of their amp cabinets can help reduce stage bleed into their guitar mics. This is especially true with some of SE Electronics' favorite guitar mics like the VR1 and RNR1 ribbons, since they naturally have a figure-8 pattern that leaves them open to whatever else is happening on stage.

Using an RF on a guitar cab or drums not only helps the FOH mix, it makes the multitrack of a live show significantly easier to mix. Until now, SE Electronics' FOH engineer clients have had to devise their own custom-assembled solutions to manage this problem. With the SE Electronics guitaRF, however, these custom rigs are now available as an off-the-shelf solution for anyone looking to emulate their favorite guitar sounds. Better yet, this can be done with minimal stage bleed and coloration.

The Hardware - The LDC/ribbon mounting hardware is adjustable across three axes - vertical, depth, and lateral - so you can find the perfect spot for any mic, whether in a shockmount or just on a clip. This allows you to position both capsules perfectly in phase - or to spread them apart to capture the sounds of both the edge of the cone and the dust cap. The entire filter and mic assembly can also be moved up and down to position it precisely over the perfect spot on the speaker cone - or, if needed, the filter can be removed from its base and mounted on any mic stand for complete flexibility.

The Filter - Acoustically, the guitaRF is very similar to SE Electronics' RF-X, with a four-layer acoustic filter design comprised of the outer composite panel, a layer of acoustic-grade wool, an air gap to help with low-frequency isolation, and an inner acoustic foam layer. The SE Electronics guitaRF also has an integrated pass-through hole with a rubber-finned grip that securely holds almost any dynamic or small-capsule mic on the market. A double-cable clip is also provided that attaches to the back of the filter, so you don't need to worry about dangling mic cables that could accidentally tug your mics out of position.

When you put a microphone in front of you, it doesn't just hear you - it hears the room around you. Even if it's a cardioid mic and is listening mostly to just you, it's still picking up reflections from your voice or instrument that are bouncing off the walls and coming back to the mic. The goal of acoustic treatment is to minimize the pickup of such reflections so your primary sound source comes through as pure as possible.

Some materials are good at absorbing or reflecting particular frequencies - for example, foam absorbs highs really well, but does nothing for lows. sE's patented multi-layer technologies absorb frequencies evenly across the whole frequency spectrum. This is what makes the SE Electronics Reflexion Filter™ unique, and makes it the choice of recording artists across the globe - whether they're working in untreated rooms, or working in a professionally-designed studio and just need a little more isolation.
