The Crimson Audio Orange SM57/SM58 Modification offers a rich and rounded character, to give your SM57 and SM58 a more ribbon like sound, while remaining familiar. This custom tuned premium grade transformer mod is pre-mounted in a replacement handle.

The Crimson Audio Orange SM57/SM58 Modification provides a full bodied and warm character, that gives your Shure SM57 and SM58 a more ribbon like sound. A deeper low end, smooth rich mids, and a soft yet airy top end, making it sing on guitar cabs, and adds meat to a snare. It also performs very well on kick drums, spot micing on hats, and on vocals. Pair your Orange 57 with a Crimson Audio Transformers Mogaine, and experience the 57 like you never thought possible! The Crimson Audio Transformers Orange will make you fall in love all over again.

This unique mod is not only affordable, but easy to do yourself. It only takes a couple mins, and some very basic soldering skills.

This mod also works with the Granelli Audio Labs G5790, and the Shure 545SD Front End Audio has gone the extra mile to make this an al la carte that is super simple.

1) Pick your Crimson Audio mod
2) Pick your Shure cartridge (if you are not installing on a preexisting mic)
3) Add a Granelli Labs 90 degree conversion kit (or not)
4) Install the mod (or build it, if getting a new cartridege)
Alternative 4) Let us install the mod for you (if you don't want to install it yourself).
5) Enjoy!

When you want us to build the mic (or install it on a cartridge you provide, for a small service fee, we will QC the parts, assemble the mic, QC the finished mic, and get it on the way to you - so you can just rock and roll right out of the box.

Don't forget about the killer White.SM, Yellow.SM, and Blue.SM mods, brought to you from Crimson Audio and Front End Audio!

    Crimson Orange 57 mod
    Jay Matheson

    Most engineers that have been around a while have an extra 57 or two around so this is the least expensive way ever to diversify your mic locker with a new go to guitar mic. Electric guitar often sounded a bit fizzy on top with stock 57s so the thicker sound of the Orange Mod is just what is needed. If anyone wants to record electric guitar in our studio, the Crimson Orange Modded 57 is the 1st mic that goes on the cab. I'd say 80% of the guitar and sometimes bass cabs that I record use at least 1 of these mics.

    Eliminates need for EQ, pleasant break up when pushed hard
    Jeremiah Shifflett

    Feels just like you are pushing a SM58, but you get a little more low-mid and presence, very smooth sounding. Eliminates my need for an EQ which is awesome. Nice break up, making it sound ribbon like when pushed hard. Quality product and great service too. Easy install if you can do basic soldering. Highly recommend this for those who like a 58 but often bump the low-mid and presence with an EQ. FYI it has a black wire that is not needed in all situations. You can either body ground it or clip/tape it up out of the way.. #TriggerWarning coming 12/21/22

    A really easy mod that sounds great.
    Booji Boy

    The Crimson Audio Orange mod turns a modern 57 into an older Sm57 unidyne with less honk. I use these on guitar and Tom bottom the white mod is killer on snare.

    the best choice for this magnificent microphone
    AlessioBlve from Italy

    over the years I have tried several SM57s, and I have noticed how the quality has changed a lot, mainly with the passage of production from the United States to Mexico. The transformer was simply changed. This Orange interpretation of the SM57 returns the original sound of the SM57 Unidyne III in an interpretation with a greater range of frequencies both high (softening them) and low, the best choice for this magnificent microphone, absolutely recommended for both vocals and players. acoustic and electric or percussive instruments.

    Great Mod to a Stock SM57

    I was pleasantly surprised with this transformer mod. It adds a bit of low end and takes away some of the "honk" and grittiness from the highs from the stock 57. It's like having built-in EQ, making it much easier to post-process.

    Crimson Orange SM57 MOD
    Chris Powell

    Much better sound from an SM-57 with this modification. I can't see myself ever putting a stock 57 on a snare drum or guitar cab again after owning 2 of these.

    Chunky and crisp
    Taylor Young

    I was in the market for a new Ribbon, and I got a few suggestions from friends. Then I remembered the Orange mod from when I bought the Yellow and White versions. I tested it out on a session and was very pleased. Truthfully I hate the SM57, it’s awkward and unpleasant to my ears, but all of these mods really fix what I dislike in different ways. The Orange mod on guitars sounds super beefy, and you can cleanly boost anywhere in the low range for a nice chunk. It’s still got brightness to it, but not in that unpleasant normal 57 way. There’s not as much sizzle like the Yellow version but still plenty of bite.

What We Think


The Crimson Audio Orange SM57/SM58 Modification s my personal favorite. I love it on a 57. Being a guitarist, the SM57 on a Marshall Half Stack (what I play) is a classic tried and true set up. But there is a touch of mid honk in the SM57 (and a Marshal is almost pure mids to begin with), plus the rich smoothness of a ribbon really tames the upper mid bite of a Marshall. So having the on a 57 cartridge maintains enough of the SM57 sound that is so familiar and comfortable. The ribbon like character of the, makes it great on guitar cab, bottom snare, hi-hats, and vocals.
