sE Electronics guitaRF: A Reflexion Filter and Dual-Mic Mount Built for Guitar Cabinets

The sE Electronics guitaRF is a portable reflexion filter and integrated dual-microphone mount engineered specifically for recording and reinforcing electric guitar and bass amp cabinets. It combines a four-layer acoustic filter, a two-mic mounting system and precise fine-positioning hardware on a self-supporting triangular steel base. Where a standard reflexion filter is optimized for vocals, the guitaRF is purpose-built to tame the stage and room bleed of loud amplifiers while letting an engineer dial in the exact spot on the speaker. It is a touring and studio favorite for anyone who mics cabinets seriously.

Four-in-One: Filter, Isolator, Dual Stand and Positioner

The guitaRF combines four tools in one: a reflexion filter, an acoustic isolator, a dual-mic stand and fine-positioning hardware. This integration replaces a cluttered arrangement of separate stands and clamps with a single, purpose-built unit dedicated to the amp cabinet. Because everything is mechanically linked, the mics, the filter and the cabinet stay in a fixed relationship once set, so the tone you dialed in is the tone you keep. For the gigging or recording guitarist, that means faster setup and a repeatable sound from session to session.

Four-Layer Filter That Reduces Stage and Room Bleed

At its core the guitaRF is a four-layer acoustic filter, built from an outer composite panel, an acoustic-grade wool layer, a low-frequency air gap and an inner acoustic foam layer. Positioned around the close mics, it absorbs and diffuses the sound from other instruments and the room before it can leak into the cabinet mics. On a loud stage, this reduction in bleed is what keeps a guitar track focused and separated instead of washed in drums and vocals. In the studio, the same isolation yields a tighter, more editable amp sound with less of the room baked in.

Holds Two Mics at Once for Blended Cabinet Tones

The guitaRF's standout feature is an integrated mount that holds two microphones on the cabinet at the same time, typically a large-diaphragm condenser or ribbon paired with a dynamic or small-capsule mic. A pass-through hole with a rubber-finned grip secures the second mic so both capsules sit locked in a fixed relationship. Dual-miking a cabinet is a classic pro technique because blending two microphones captures more of the amp's character than either can alone. With both mics held rigidly together, the engineer avoids the phase drift that plagues two loose stands and gets a consistent, full blend every take.

Three-Axis Fine Positioning Over the Speaker Cone

The guitaRF adjusts across vertical, horizontal and depth axes so a mic can be aimed precisely at the dust cap, the cone edge, or any blend between them. Where a mic sits on a speaker dramatically changes the tone: aiming at the center cap yields a brighter, more aggressive sound, while moving toward the cone edge warms and darkens it. Because the guitaRF lets you set that position exactly and lock it, you can find the sweet spot once and return to it reliably. Fine, repeatable placement also keeps the two mics phase-aligned, avoiding the hollow cancellation that comes from careless positioning.

Triangular Steel Base or Mic-Stand Mount, Trusted by Touring Engineers

The guitaRF sits on its own triangular steel-plate base on three rubber feet, so it can stand independently on the floor in front of a cabinet, or mount to a standard mic stand when preferred. The heavy steel base keeps the whole assembly stable next to a loud, vibrating amp without creeping or tipping during a performance. This road-ready design is why the guitaRF is a favorite of professional touring and studio engineers who need reliable cabinet miking night after night. For the guitarist who wants a pro-level, repeatable amp sound on stage or in the studio, it is a complete cabinet-miking solution in one unit.
