An all-around superb sounding, versatile, and sturdy mic for recording voice, percussion, and guitar. Substantial bottom end, silky vocal reproduction, great SPL and the adjustable response make this the workhorse in my studio and for the stage.

A ppearances are deceiving sometimes. Tweak presses a button on Tweakland's Magic Console and a glass display case of microphones rises out of the floor.  Tweak says, "think of the microphone as a marriage".  Yes.  As something you want to spend the rest of your life with.  "Choose carefully".  Newb...

The Sennheiser 421 is a large diaphragm dynamic microphone that came out originally in the early 60s and quickly became known as a really good sounding robust mic that could handle high spls.

I remember this mic back in the 70's at a 50k AM station I worked at in California...Always a great broadcast mic because it could be worked from any angle...Mellow sound...Excellent clarity...I am a bit pissed it is being sold at such a great price...I paid much more for mine..

I love the sound of this when paired with my SM57 - they go great together. The SmM57 gets the highs and the mids and the 421 gets the darker mids and great lows.

Studio microphone jack or live, drums, amp, copper ... OVERALL OPINION It is a very good mic. Quite versatile, I use it mostly on the toms battery. I also used a guitar amp and a bass amp.

Although the Sennheiser company has been making all types of microphone in Germany since the end of World War II, it's probably fair to say that its most iconic designs (like the 421 and the 441) are moving-coil dynamics rather than condensers.

RE27 or MD421 II ? That was the choice for me. No phantom power stuff that requires unnecessary interfacing etc. After hearing both on air, and comparing the technical specs of many, many, microphones the most natural and to my ears and also has a unique sound, the Sennheiser won the battle.

I found it to be too warm and harsh for video game commentaries and vocal work. SM7b keeps knocking all these cheap mics out. It's natural. I need to get natural mics! If you want warmth and harsh and a muddy sound then get this.

I was so please to get this microphone. Clean and clear and very robust. An absolute classic of the music industry. Gough whitlam spoke into one on that terrible day in November during the constitutional crisis, the Beatles used them all over the world seen lots of photos of that.
