Sennheiser MD 421-II Dynamic Cardioid Microphone

With its high SPL handling and 5-position bass roll-off, it's no wonder that the versatile Sennheiser MD 421 is one of the world's most popular microphones.

A classic microphone on drums, guitar amps, bass amps, vocals and more, with a frequency response spanning from 30 Hz to 17 kHz, the Sennheiser MD 421 II serves as a great multipurpose dynamic mic to have in the studio. It holds up well to high sound pressure levels (SPL), making it a solid choice on any loud source. This baby also comes with five bass roll-off positions to give you more control of its deep low-end response, unwanted bleed from nearby instruments. It hosts solid circuitry and is built with clear sonic reproduction and durability in mind, so you can always count on getting the best sound out of your instruments during sessions. Your Sennheiser MD 421 is also a solid choice for broadcast voiceover. And if you're recording super-loud, aggressive rock or rap vocals -- the 421 can handle them, too!

Multiple Bass Roll-off Settings

Built with internal bass tubes and delivering accurate bass all the way down to 30 Hz, this mic dishes plenty of lows when that's what you need. And when you don't, five different low-end filters gives you the flexibility to dump room rumble or cut out unwanted bleed from bass instruments.

The Go-To Mic for Recording Toms

Armed with Sennheiser MD 421s, you can comfortably mic your toms without worrying about cymbal, snare, or kick drum bleed. The 421's cardioid pattern makes it a natural for keeping out instruments next to it and from behind. And being a large-diaphragm dynamic microphone, your MD 421 II gets you a good read more directional tonal capture. There's a reason you see 421s hanging over so many toms -- this classic mic is "the" go-to choice for this hard-to-capture instrument.

Durable with Clear Sonic Reproduction

Your MD 421 II gives you clear, mud-less audio capture. Its acoustic components are housed in an enclosed chassis to keep out dust and provide resistance to changes in room moisture levels. This dynamic mic also stands up strongly to high sound pressure levels before distorting -- reliably embracing the loudness of drums and amps in a consistently clear and clean fashion. Hang it in front of horns, and the MD 421 will hang right with you. Talk about a tough mic!

Deep, Wide Frequency Response

The frequency range of your MD 421 II gives you a lot of room for recording different sources. Aside from loud instruments and sources like drums and amplifiers, this microphone works well for capturing broadcast voiceovers -- or anything you'd use a cardioid dynamic on. You'll really be adding a colorful and versatile tool to your studio's mic closet with this popular large-diaphragm dynamic microphone.

Finally bought a couple of these for use primarily on drums, guitar cabs, & horns. I'm a former music performance major and audio engineering school grad, & have been building my studio for over 15 years. Got the 421's in the mail and immediately used them on a drum session with rack & floor tom, running through API preamps. The sound was excellent! I was very impressed with the tonal quality, the ambient pickup (or lack thereof), and will probably order at least two more. Different people have different opinions of this mic, but it's a workhorse for a reason. Every mic has its own 'thing', and this mic does what it does amazingly well. Dynamic mics are not condenser mics, and they have a different sound / vibe. The roll-off switch will come in handy for mic'ing guitar cabs, bass cabs, low toms & kick drum, and anything in close proximity. These mics handle louder sources very well. Of course, the only downside to this mic is the notoriously bad clip. It's okay if you don't have to move it, such as placing on drums or guitar cabs in a session. Obviously not meant to be moved once set in place. However, a very, very good dynamic mic that will get used a ton in my studio.
