Introducing the M1

The M1 is the Andreas Grosser and Eckehard Dux engineered collaboration with pro audio designer, Andrew Myburgh. A brand new vintage inspired tube microphone.

The M1 has a German made Mylar M7 capsule made by Siegfried Thiersch and a Russian military grade long life tube. Its body and mechanics are built to last a lifetime. The M1 build quality and appearance are unprecedented.

The M1’s amplifier has an incredible linear frequency response with minimal cut off below 30Hz or over 20Khz. With two custom built transformers; one in the mic and another in the power supply, the amplifier design, combined with the German made capsule and the new capsule basket design give the M1 its unique sound.

The M1 also has a super low noise floor, a monster output and handles SPL better than your favourite FET kick drum mic does. Variable polar patterns and true cardioid is a main feature.

    Myburgh M1 Featured by Eric Allen for Vintage King, USA

    “What happens when you bring together a team of designers who were raised on the strong tradition of German tube mics? Microphone magic! Created in collaboration by noted U47 tech Andreas Grosser, design engineer Eckehard Dux, and engineer/producer Andrew Myburgh, the new Myburgh M1 microphone is certainly a beauty.”
