Text from Earn Trumpet Labs' website:

Ear Trumpet Labs was founded in Portland, Oregon by inveterate tinkerer and former software engineer Philip Graham, who built his first microphone for his daughter Malachi when she wanted to record her own songs. In acoustics and electronics he pursued an accurate, natural sound using carefully selected discrete components. He assembled the bodies from parts he had at hand in his basement and gleaned from hardware scrap stores– but applied a design sense from the peak of industrial style. Soon, musician friends were asking to use his mics, and he refined the designs to excel for live sound. The basement lab became his full time passion.

With the help of numerous musicians spreading the word, we've grown to a small workshop with three craftspeople building microphones for customers worldwide. Philip's daughter Malachi now helps run the business (and her two bands). Everyone in the shop is a musician, and we try never to lose sight of our goal of putting affordable, great quality tools in the hands of working artists.  

At Ear Trumpet Labs we try to foster equality of access to jobs and performance opportunities for people and communities that have been underrepresented and underserved. We advocate for the active pursuit of diversity of gender, race, culture, and sexual orientation in festivals, booking, engineering, and manufacturing. Kids and young people especially need to see that any future could be theirs, for us all to have the richest culture and economy we can.


Nadine is a medium-large diaphragm condenser mic specifically designed for use on upright basses. The low end is tuned to give a flat response at the mounting distance, and the cardioid pickup pattern provides very natural sound by picking up as much of the surface of the bass as possible, within the constraints of the close placement. There's great rejection off the back of the mic, allowing use with stage monitors.

Physically, the mic is separated into the body, which securely straps to the tailpiece with velcro elastic, and the head, which mounts easily between the strings above the tailpiece using a rubber grommet. The 14-inch Mogami cable that connects the two parts makes it easy to place the mic ideally on any bass. This mounting system makes Nadine both easy to move from instrument to instrument and secure enough to leave on one bass permanently. After years of being asked for a mic specifically designed to meet the needs of the acoustic upright player, we think we've found the best design yet for this demanding application.
