The MXL R77 Review

In this article, we’ll talk about the MXL R77 ribbon microphone. This microphone is the upper end of M exhales ribbon microphone offerings. It actually features a 20 Hz to 18-kHz frequency response, a figure of 8 pattern SPL levels of 135 dB, and features a 1.8-micron aluminum ribbon element. 

One thing you’ll notice is it looks dramatically different from the brother of the R44. It is a classic kind of pill-shaped microphone and it has a shiny chrome and gold finish which is eye-catching and that is necessary for today’s marketing needs, have a little eye candy works well in a studio. The microphone also comes with a nice wood case that has a burgundy felt kind of velvet lining. It comes with a cleaning cloth that will help keep oil and dirt and fingerprints off the microphone and keep it looking real nice and functioning for a long time. It comes with a small desktop mic stand so that you can use this in broadcast applications for radio internet radio or podcasting. And it also comes with a Megami mic cable microphone that also features a hard mount Yoke that your mic stand attaches to and you’ll have to bring the mic out a little bit to attach your mic cable.

Another difference that I find from this mic compared to the R44 from MXL is that the front side is the brighter side and the backside is the darker side. Though there’s less of a difference and it seems to be a more neutral microphone and the sound as where the R44 has a little bit of color and there’s a little more dramatic difference between the front and back. However, that does not mean that this microphone is not versatile it’s extremely versatile and works well on every application. I find it very very pleasing on drum room, vocals, electric guitar cabs, and acoustic guitar. It works well with the dynamics of each of those instruments. The brighter cleaner sound of the front side works really well with adding a nice presence and cut to vocals and drum room. And the darker more I guess natural-sounding side of the back works very very well with electric guitars and giving you a nice full thick sound that you would want in that application. It is a reasonably priced microphone so it is easily within grabs for home studio and gals and it is a great addition for project studios as well. All in all, it is a very nice-looking microphone, a very versatile microphone internally wired with Megami. Comes with the cabling and all these other nice accessories that you get at a great price point and would be a great addition for those looking to add a ribbon microphone to their arsenal.


MXL’s R77 is a solid performer at a realistic price, so unless you’re set on buying the cheapest ribbon mic you can find, it should go on your list of ribbon models to check out. It makes everything sound warm and cuddly with a smooth top end, and in a way that EQ never quite seems to match. It also looks pretty ‘pimped’.
