"I have an [AKG C414 TLII](http://equipboard.com/items/akg-c414-tlii) for vocals and acoustic guitar, a couple of Royer R121s and some [Shure SM57](http://equipboard.com/items/shure-sm57-instrument-vocal-mic) and [58s](http://equipboard.com/items/shure-sm58-vocal-microphone) for guitars, and that's it." - [Ken Lawrence](http://www.soundonsound.com/sos/jul13/articles/it-0713.htm).more
"The band tours nearly 300 days a year so to keep things running as efficient as possible Barakat uses a Kemper Profiler so he can quickly access all the band’s recorded tones and even shared settings given to him by Mark Hoppus of Blink 182. For his clean tone he’s using an AC30 model that’s miked with a Royer R121 ribbon microphone and for the more aggressive stuff the core tone is sampling from Barakat’s Budda Superdrive 30."more
"I use a Royer R-121 and Shure SM7 and sometimes a Sennheiser MD 421 on my cab. That’s going through a Retro compressor, a Burl Mothership [analog to digital converter], an Empirical Labs Fatso compressor, and a Dangerous Music BAX EQ. That signal chain’s amazing, but everything else is just coming through my pedalboard."more
"In general I used both Shure SM57 and Royer R-121 ribbon mics, a few inches back, just off the center of the cone, give or take an inch or two depending on the part. When you back the mics off a bit, it can help a part sit in a track better, especially if there are more that two guitar parts."more
There are few things I DON'T like to use this on. Really shines on Guitar cabs, drum OH's, warm on acoustic especially when paired with a condenser to add in some "sparkle". Also will frequently pair it with a 57 or other dynamic & blend to taste (always check you phase!). These are hardly secrets, these techniques are widely used but for good reason. It sound so damn good!
Can handle high SPL (I however can not break the habit of handling them while setting up/take down/etc like the much more fragile vintage ribbons of the past). It's another "essential" in my locker.
