The Cactus delivers a commanding, intimate presence with larger-than-life detail that is reminiscent of the world’s finest and most well respected vintage designs. At a distance, the Cactus’ B7 capsule delivers every nuance in the room, with finely focused resolution and clear, musical frequency response to the extremes of the audible spectrum. Up close, with its detailed highs and smooth midrange, the nine-pattern Cactus excels at delivering a vocal or solo track right to the front of the mix. The amplifier is a transformer-balanced single vacuum tube sub-miniature pentode in a triode mode, along with the highest quality hand-selected electronic components to insure absolute minimum noise and distortion.

At the heart of the Cactus is a multi-pattern variation of the B7 Bottle microphone capsule. This large diaphragm, single back- plate capsule is our contemporary version of the unmistakably warm sound ascribed to the great 1950’s tube microphones. A boost in the upper midrange response brings out just the right amount of intimate detail for vocal tracks, without emphasizing sibilance. The B7 exhibits a silky, slightly compressed tone, with less high end presence boost than the B6/B0 Bottle capsules and related capsules in our Mouse and Blueberry microphones. Its smooth, natural highs and abundance of tone make the Cactus ideally suited to saxophones, electric guitar, organ, acoustic bass, and other solo instruments as well. Acoustic guitar, hand percussion, drums, and  ther critical high end sources also shine in front of the Cactus. The precision-crafted Blue electronics add an extra measure of presence that enables the most delicate sounds to cut through a mix, even when miked at a distance or mixed at very low levels.
