Crimson Audio Blue SM57/SM58 Modification

The Crimson Audio Blue SM57/SM58 Modification builds on the popular White transformerless Shure modification, but expands on it, by tailoring the character for vocal applications. The Blue.sm also includes a modified Crimson Mogaine circuit to defeat the normal loss of output that occurs when you remove the transformer!

The Crimson Audio Blue SM57/SM58 builds upon the transformerless Shure SM57 modification, expanding on what the White.SM Mod started. The White.SM eliminated the hassle and mess of the transformerless mod, as well as solved the output loss problem. Now the Blue.sm steps in and takes the transformerless mod a bit further. It Blue.SM does this with a tweaked circuit that tailors the character to improve performance in vocal applications. This cool design provides more cut when used with an SM58 cartridge, and more silky smoothness when used with an SM57 cartridge.

Like the White.sm, the Blue.SM solves the problem of loss in output you get from the transformerless mod. Again achieved by providing a scaled down version of their awesome Mogaine pre-preamp device, built into the handle. So you get all the good from the mod (now tweaked for vocals), and none of the bad!

As with other Crimson Audio Mods, the Blue.SM is also compatible with the Granelli Audio Labs G5790 90 degree conversion elbow? And, once again - Front End Audio has gone the extra mile to make this an al la carte that is super simple.

1) Pick your Shure mod

2) Pick your 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 building from scratch)

4.5) Let us install the mod for you (if you don't want to install it yourself).

5) Enjoy!

Don't know how to install the mod, or simply don't want to? Let us do it! 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.

And there you have it. That easy, that flexible, and well worth it. Also, don't forget about the killer Yellow.SM, Orange.SM, and White.SM mods, brought to you from Crimson Audio and Front End Audio!
