Will these work with both the Shure SM57 and SM58
Yes. All Crimson Audio Mod Squad handles are compatible with both Shure SM57 and SM58 microphones. Whether you're using an SM57 in the studio or an SM58 for vocals, the Mod Squad system allows you to transform the sonic character of the microphone while retaining the trusted Shure platform you already know and love.
Can Front End Audio build the microphone for me?
Absolutely. If you'd rather skip the installation process, Front End Audio can professionally assemble your Crimson Audio modified microphone for you. Simply select the complete microphone option when purchasing, and we'll handle the build so it's ready to use right out of the box.
Is the modification permanent?
No. The modification is fully reversible. If you ever decide to return your microphone to its original configuration, the stock handle can be reinstalled using the same connection points.
Which color is the most popular?
Orange and Yellow are by far the most popular choices among Front End Audio customers. The Orange Personality is favored by engineers looking for a warmer, fuller, more vintage-inspired character, while the Yellow Personality is a favorite for snare drums, guitar cabinets, percussion, and other sources that benefit from additional punch and presence. Many customers eventually purchase multiple/all personalities so they can tailor their microphone to different recording situations.
Can I install the handle myself?
Yes. The modification is designed to be straightforward and requires only a few simple solder connections. Many customers choose to purchase the handle and perform the installation themselves.
Do I need any special tools to install the handle?
No specialized equipment is required. A basic soldering iron, solder, and common hand tools are typically all that's needed for installation. If you'd prefer not to modify yourself, Front End Audio can build the microphone for you.
