The Crimson Audio White SM57/SM58 Modification is a Front End Audio exclusive, custom tuned transformerless modification handle for your Shure SM57 or SM58. Simple to install, the White modification handle offers an open and balanced sound, without the loss of output gain – making it a workhorse!
The Crimson Audio White SM57/SM58 Modification handle really changes and elevates the standard SM57 and SM58. We all know, own, and love the Shure SM57 and Shure SM58. Whether at home or professional studios, the SM57 and SM58 have been go to mics for guitar cabs, snare drums, vocals, and more. However, we sometimes want a little more richness, depth, or air from these mics. Sometimes we want a little less, like a little less mid honk. Introducing Crimson Audio! Crimson Audio, along with the help of Front End Audio, has designed a series of fantastic transformers, pre loaded in replacement handles, ready to evolve your SM57 and SM58!
How does the White handle sound?
The Crimson Audio White SM57/SM58 Modification handle gives you the transformerless Shure SM57 modification, without the hassle, and big mess. Additionally it features a scaled down version of the Crimson Audio Mogaine circuit so you do not have the output gain (just apply phantom power). With all this, the White Modification handle gives you a more open, balanced, smooth, and natural sound. So now you get all the benefits of the transformerless mod, with out the gain loss or headaches, and it only takes a few minutes of soldering. Want more!? Don't forget about the other modifications handles that we offer. Check out the Yellow.SM, Orange.SM and Blue.SM mods, brought to you from Crimson Audio and Front End Audio!
Crimson Audio White SM57/SM58 Modification Options
Front End Audio has made it easy to build the modification handle of your choice. However if you have any question please reach out to us and we will be happy to assit you in deciding what options best fit your needs.
- Select Your Cartridge: Add either an SM57 or SM58 cartridge (with our without grill) to your handle. Many times we find customers will have a extra SM57 or SM58 laying around their studio that they dont mind using for this modification. If this your situation, then there is no need to add a cartidge. Howerver, if you dont want to canabilize one of your existing microphones then this is your solution.
- Add a Granelli Audio Labs Handle: The Granelli Handle option is a 90 degree elbow that works seamlessly with the Crimson modification. It gives your mic a 90 degree angle to help improve your mic-placement options on drums, guitar amps and bass cabinets. This is a super cool addition which adds versatility to your microphone.
- Modification: This unique modification is not only affordable, but easy to do yourself. It only takes a couple minutes with some very basic soldering skills. However, if you want to skip the extra work or don't have the tools, then we are happy to do the modification for you. When Front End Audio does the modification we will QC all parts, assemble the microphone, QC the finished microphone, secure it in its own zippered mic bag*, and get it on the way to you typically within 1-2 business days - so you are ready to go right out of the box!
*Zipper mic bag is included for free only when Front End Audio does the modification.

Effective, simple to do, sounds great
Apr 19th 2024Purchased to upgrade some of my many SM57s to be more transparent on woodwinds and the like. Easy install, sounds first difference is a bit more gain than the stock transformer, and second biggy is more extended high end. Lastly, a bit less honk and compression. All desirable. Well done. PS: newer SM57s come with a ground wire to metal strap in the body between the two interior side walls. Might be a future improvement possibility but depends on the grounding of the circuit, of course. Older SM57s don't have this ground connection to the body, and there were no noises or other artifacts in my initial trials.

I'd Rather Have No Transformer Than The Stock Shure SM57 Transformer
Apr 16th 2024I have most of Crimson Audio SM57 modicifcations. I love the White on snare top and bottom. The sound characteristic is a big clear punch! It's a simple mod without having to remove the original shure transformer. The white mod requires phantom power because it needs the power to boost the mic back to its original output level. You just solder the two points Green is + and yellow -.

Crimson Audio White SM57 Mod
Jun 16th 2017Great product the modified 57 on snare drum punchy and the sound is very open. On a single guitar cabinet from the speaker out of a vintage 1965 Princeton Reverb the Crimson White held its own against a very high end Samar VL37 ribbon mic.
