Electric guitars tend to dominate conversations about guitar microphones, but choosing the right mic for acoustic guitar will make or break the track.

 

Instead of capturing a speaker pushing serious SPL, you’re trying to reproduce the combination of strings, pick attack, body resonance, and the air moving around the instrument. That’s where a condenser like the e 614 makes sense.

 

The e 614 is a compact supercardioid condenser with a nearly flat 40 Hz–20 kHz frequency response and fast transient response. Those qualities help it capture the immediate attack of your pick or finger against the strings while preserving the upper-frequency information that gives an acoustic guitar its openness.

 

Placement will dramatically affect the result. Pointing directly at the soundhole will generally produce more low-frequency energy than most mixes need. A classic starting point is around the 12th fret, angled slightly toward the body. Move toward the bridge for a different balance of body and string detail, or back the microphone away when you want more of the room.

 

 

 

Calling the MD 441-U versatile is almost underselling it. It’s a dynamic supercardioid microphone with an unusually extended 30 Hz–20 kHz frequency response, five-position bass roll-off, switchable high-frequency boost, excellent rejection, and a reputation for the detailed reproduction more commonly associated with condenser microphones.

 

Ask around or look online. You’ll find countless audio engineers who use the mic on just about everything. They even prefer it over many of their condenser mics.

 

That said, it is a legendary guitar microphone in its own right.

 

Put it in front of an electric guitar cab, and you get the durability and high-SPL capability you want from a dynamic mic, but with enough extension and detail to capture more of the amplifier’s complete character. The onboard bass and treble controls also provide considerably more freedom to tailor the microphone to the source.

 

You’ll be surprised how complete a picture a single 441 gives you. Where other dynamic mics come to life when blended with a ribbon, the MD 441 is a one-and-done on high-gain stacks, bluesy combos, and even acoustic guitar.

 

The MD 441-U was never meant to live in one lane. For a guitarist building a serious project studio or an engineer who wants microphones that can earn their keep across an entire session, this is the Sennheiser for you.

 

 

 

The MD 21-U may be the wild card in this group. Unlike the directional microphones we’ve covered so far, the MD 21-U is omnidirectional. Originally built around broadcast applications, it combines a uniform frequency response with an extremely rugged design and resistance to handling, wind, and pop noise.

 

That omnidirectional pattern changes the equation when you put one in front of a guitar amp. Instead of aggressively rejecting the sound around the cabinet, the MD 21 lets more of the surrounding environment in. In a good-sounding room, that can be exactly what you want.

 

This mic really shines on electric guitars, especially in high-gain guitar tones. Its unique response captures a wonderfully raw, snarling quality without losing low-end power. Will it replace your e 609? Probably not. But it’s an extremely inspiring guitar mic in its own right.

 

It also opens up different placement possibilities. Try it where you’d normally place a close mic, then start backing it away from the cabinet. As the distance increases, the room becomes increasingly important to the sound.

 

 

 

 

If your priority is miking a guitar amp quickly, reliably, and affordably, start with the e 609. It was made for the job, and its flat body, supercardioid pattern, and purpose-voiced sound make it equally useful for gigging guitarists and live-sound engineers.

 

Want that same general concept with additional tonal control? Step up to the e 906.

 

Are you looking for the iconic sound of the MD 421? Ahem…buy an MD 421-II or MD 421 Kompakt.

 

Recording acoustic guitar? The e 614 gives you the detail and transient response of a condenser.

 

Want one of the most versatile dynamic microphones Sennheiser makes? That’s the MD 441-U.

 

And if you want to get away from the usual close-miked guitar sound and experiment with something that brings its own character to the track, try the MD 21-U.

 

Always remember, the best guitar microphone isn’t the one with the most impressive specifications. It’s the one that gives you the guitar sound you’re after as quickly, efficiently, and beautifully as possible. So give them all a try, because who ever only uses one mic?

 

As the name suggests, it takes the MD 421's performance and packs it into a significantly smaller package. It maintains the cardioid pattern, 30 Hz–17 kHz frequency response, ability to handle very high SPLs, and signature voice of the 421 family. It just does it in a housing that stays out of the way onstage and in the studio.

 

If the e 609 is the specialist you buy specifically because you need to mic a guitar amp, the MD 421 family represents the opposite philosophy. You should buy one because you need that mic for your guitar amp.

 

Introduced in 1960, the MD 421 developed a reputation for working on almost anything you put in front of it. Drums, vocals, broadcast, brass, bass, and, of course, guitar amplifiers have all become part of its résumé. Its magic midrange and ability to handle extremely loud sources made it especially well suited to the increasingly powerful amplifiers of rock music at the time.

 

That still holds true today, and the MD 421 remains one of the most common dynamic microphones used to record electric guitars. It gives you the articulation and midrange definition you expect from a close dynamic microphone, but with more low-frequency extension to keep a big tone sounding big. That makes it an excellent choice when you want a fuller picture of an amp rather than focusing primarily on its upper-midrange attack.

 

And like the e 906, the MD 421-II also gives engineers a five-position bass roll-off control. That’s useful when proximity effect or a particularly thick guitar tone has more low-end than the mix needs. Instead of fixing everything later, you can start shaping the sound at the microphone.

Ask a group of engineers for the best microphone for a guitar amp, and a few will always be mentioned. That’s because, while there isn’t one universally “correct” guitar mic, there are mics that define how we hear the instrument. We’re proud that many of those industry go-tos say Sennheiser.

 

There are our older classics, like the MD 409, MD 421, MD 441, and MD 21. And there are the more modern designs, like the e 609 and MD 421 Kompakt. These microphones are regularly found in front of guitar cabinets all over the world. And others, like our e 614, are mic-locker must-haves for acoustic players.

 

Countless guitarists and audio engineers agree: if you’re just getting into recording electric guitar or live sound, the e 609 is the logical place to start. But if you’re an experienced engineer, we offer plenty of options to tempt you with. Here are some of our favorite Sennheiser microphones for capturing guitars onstage and in the studio, along with what each brings to your sound.

 

 

 

There are versatile microphones that work well on guitar amps, and then there are microphones born for the job. The Sennheiser e 609 falls firmly into the second camp.

 

This dynamic, supercardioid instrument microphone has a distinctive flat, side-address body that makes it dead simple to place the capsule directly in front of a guitar speaker. But the mic’s shape isn’t just an aesthetic choice. Loop the XLR cable over your amp, then hang the mic directly in front of the grille. No mic stand required!

 

For live sound, that can be a bigger deal than it sounds. One less stand means one less thing crowding a small stage, getting kicked by a singer, or shifting halfway through a set.

 

Then there’s the sound.

 

The e 609 has the direct, punchy response guitarists generally want when close-miking a cabinet. Put it near the center of the speaker for more upper-midrange bite and definition. Move it toward the outer portion of the cone when you want to soften the top end and emphasize more body. Small movements matter here. An inch can change your guitar sound considerably.

 

Search YouTube for e 609 demos, and you’ll hear a ton of high-gain guitar. The mic loves these tones and more than stands its ground. But when you hear it on a clean or edge-of-breakup amp, its clearer mids and highs, and its warmer bass response start to set it apart from the pack.

 

Want an even fuller sound? The e 609 blends famously with warmer-sounding mics like ribbons. So don’t be afraid to experiment.

 

Of course, the e 609 is excellent at rejecting off-axis noise. Yet another reason it’s one of the most popular live-sound guitar microphones of all time.

 

All in all, the e 609 is a purpose-built mic that’s simple without being limiting. Any player can get a great sound quickly, even if you’ve never miked an amplifier before. At the same time, an experienced engineer can still capture a glorious guitar tone that works on a professional track.

 

If you need one dedicated Sennheiser guitar amp microphone that you can throw in a gig bag, hang in front of a cab, and use night after night, the e 609 is hard to argue with.

 

 

 

At first glance, the e 906 looks a lot like the e 609. That’s intentional. After all, it’s also a supercardioid dynamic microphone designed to hang in front of, and handle the realities of loud guitar cabinets. So, we gave it the same basic flat profile that works so perfectly.

 

The big difference is flexibility.

 

The e 906 incorporates a three-position presence filter that lets you choose between bright, moderate, and dark voicings. Instead of immediately reaching for the console, you can change the microphone’s response before the signal gets there. So even if an amp sounds too aggressive or muddy, it’s simple to get it perfect for the mix.

 

That can be particularly useful for live sound engineers working with different guitar rigs every night. A dark-sounding cabinet might benefit from a bit more presence. A high-gain rig with a lot of upper-frequency fizz may work better with the darker setting. Or leave the response in the middle position and let the amp speak for itself.

 

Like the e 609, the e 906 can hang in front of an amplifier, and its supercardioid pattern makes it a natural choice on sonically busy stages. It also has a fast transient response, which helps preserve the pick attack and immediate punch that can give electric guitar its sense of energy.

 

So, e 609 vs. e 906? Think of the e 609 as the straightforward guitar-cab workhorse and the e 906 as the option when you want the same basic advantages with more tonal control.
