Rupert Street Recording, Mixing, ATMOS & Video Production in Waterloo, ON, Canada

Bold. Versatile. Built to rock.

The Sennheiser MD 421 is a dynamic microphone with a legendary reputation for handling high SPLs and capturing rich, full-bodied sound. Its versatility makes it a studio workhorse at Rupert Street Recording—ideal for drums (especially toms), electric guitar amps, brass, and even aggressive vocals. With its five-position bass roll-off switch, it’s easy to tailor the response for any source.

The MD 421 has been a staple in studios and on stages since the 1960s and was famously used by The Beatles’ engineers at Abbey Road to mic everything from vocals to Leslie speaker cabinets.
