"Awesome mic. Killed my 251 on super-rich gospel vocals."
- Chris Fogel, Scoring Engineer ('Wolf of Wall Street') -

The sE Gemini II is the larger-than-life answer to your vocal tracking needs.

It's not just large in stature - it's HUGE in sound.

The Gemini II dual valve microphone is a no-holds-barred piece of microphone history. The dual valve design means pure valve warmth from the 12AX7 input valve, coupled with a 12AU7 valve on the output stage. The result is an incredibly large, detailed, and intimate sound – reminiscent of the classic valve microphones from decades ago, but with a thoroughly modern twist.




Most microphones use a transformer to optimize the mic's output impedance and couple the mic to the mic preamplifier. With the Gemini II, this optimization is accomplished with a second vacuum tube, negating any high-frequency rolloff typically incurred with a transformer.

This provides the Gemini II with a sparkling, pristine high-end typically only found in the most expensive solid-state microphones, while maintaining the rich, thick tonality of a tube mic.

Not just for vocals, the bass cut filter and -10dB pad make the Gemini useful for loud and heavy sources like drum room mics and booming timpani.

The Gemini II comes packaged in a wooden presentation box next to its custom shockmount and robust power supply, all within a secure and solid flight case.

"The mic is an absolute pleasure - easily competes with mics at twice the price point. Really warm and rich, yet plenty of high end sparkle. While some folks might consider it primarily a vocal mic, I've had some of my best results on acoustic instruments. It really captures mandolin and small bodied guitar nuances quite accurately."

- Bennett Dean Lewis, Guitarist (of Montreal, Lera Lynn) - sE Artist

"Awesome mic. Killed my 251 on super-rich gospel vocals."

"I used the thing on several orchestral elements at Sony scoring and it was outstanding on everything. It's the best tympani mic I've ever used, and I typically use well-maintained 47s or 49s. Really great."

- Chris Fogel, Scoring Engineer ('The Wolf of Wall Street', 'The Secret Life of Walter Mitty', 'Old School')

"The sE Gemini II is both the beauty and the beast. It demands attention, both visually in the studio, and aurally in the mix. With its clarity and detail, it's an easy go-to choice for vocals and much more."

- Bob Mallory, Chief Engineer at Paste Magazine Studios NYC - sE Artist

"The transformerless design would appear to combine the most recognizable attributes of tube and solid-state microphones, providing the expected tube warmth and low-end weight but without losing the high-end sizzle, as can happen with 'tube plus transformer' designs."

"Because of its high-end clarity, the Gemini II also makes a useful instrument microphone, its capabilities extending from acoustic guitars and other plucked instruments to percussion and wind."

- Paul White, Sound On Sound (full review)

"I am incredibly impressed by the seemingly contradictory combination of warmth, crispness and definition that was captured in the tracks by the sE Gemini and Reflexion Filter Pro...the songs we were working on had dense arrangements yet the sax cut through without ever sounding abrasive or disconnected from the rest of the track...it was a beautiful, natural sound -­ we didn't even use any EQ."

- Don Was, Producer/Engineer (Bob Dylan, Bonnie Raitt, The Rolling Stones, Willie Nelson)

"The Gemini has a unique sound with great character. One thing that was instantly noticeable about it was its upper mid to high frequency boost. After hearing some voiceover using this mic, the warmth in the bottom was also quite apparent."

"Overall everyone during the tests were very pleased with this mic and a few people were surprised that it didn’t cost more money. The mic has a quite a presence. It’s built like a tank."

- Matt McGlynn, Recording Hacks (full review)

"We were all floored by how this beastly microphone seemed to transcend the price barrier and provide AMAZING results for the money."

"If you want a mic that gives you smooth vocals, warm acoustic guitars and just leaves you satisfied from the moment you turn up the gain on this beast, look no further."

"It picks out nuances that you wouldn't expect from a tube. Adds a bit of tone, but is extremely clear."

- Assorted Sweetwater users (more reviews at Sweetwater.com)

"It's big and it delivers. This is always a go to mic for vocals in my studio. It has warmth, a sweet top end, and it just sounds right."

"Background noise is almost non-existent and it shares a spot with the best mics for this."

"Impressive to stand in front of, and impressive results. A favorite in my collection."
