Granelli Audio Labs G5790 Dynamic Microphone

The Granelli Audio Labs G5790 is a real SM57 modified to turn 90 degrees.  Granelli Audio Labs uses brand new Shure® SM57s and inserts a custom-made aluminum part with an acoustically-engineered internal sound path.  The result is a microphone that maintains the SM57's renowned durability and familiar tone while increasing functionality.

Giving engineers an edge
The Granelli G5790 gives engineers more options when miking crowded drum kits, allowing them to choose a position that minimizes unwanted bleed and does not obstruct the drummer.  It also creates a neater appearance and takes up much less space on stage when miking speaker cabinets, percussion, and a number of other sources.

Changing the shape, not the sound
Inside the handle of the SM57 is a small acoustic chamber that affects the tone of the microphone.  Our patent-pending design manages to change the shape of this chamber without increasing the air volume.  That is critical to keeping the sound that engineers know and trust.  Granelli did not adjust the frequency response, alter the pickup pattern, or change any other components inside the microphone. It's still the mic engineers love, with the mod it's always needed.

Durability and Quality
The part that we have added is machined out of a solid block of aluminum and then threaded into the original microphone's body.  Our modifications are done by hand without the use of power tools, welding or any other process that may harm the original microphone.  Each unit is individually tested after modification, and guaranteed by our two-year warranty.

The G5790 is currently in the studio with producers Eddie Kramer (Jimi Hendrix, Led Zeppelin, Kiss), Barry Rudolph (Lynyrd Skynyrd, Rod Stewart) and Brian Ahern (Emmylou Harris, Roseanne Cash) and on tour with the Dave Matthews Band, Creed, Gloria Estefan and Cirque Du Soleil.

About Granelli Audio Labs
Granelli Audio Labs was started in 2009 by John Grant of Secret Sound Studio and his friend and protégé Tony Correlli of The Deep End Studio in Baltimore, Maryland.  Each are established, full-time recording engineers and producers who have worked with platinum selling artists as well as countless Mid-Atlantic area bands.

About the G5790
After talking shop late one night, John and Tony decided that it would be worthwhile to modify one of their SM57s to make it easier to position in a crowded drum kit. They went out and got a PVC plumbing elbow and modifed one just for their own use.  Upon seeing the mic in the studio, drummers would frequently comment on it with interest, and colleagues began inquiring about how to get their own modified SM57.  It became clear right away that this modification would be very useful both in the studio and live.  So after many designs, tests, and refinements, the labor of love grew into a new, high quality product that they call the G5790.  This microphone can now be found in major recording studios and on the road with professional sound companies and freelance engineers all around the world.
