I am fairly new (about a year) with ribbon mics. But all of us at our studio loves to use them. we have a royer 121 and a pair of cascade fat heads. we find that they seem to work great on just about anything you use them on, but since we dont want to use the same mic for everything we constantly switch it up. But I am finding that I really like it on guitars (acoustic and electric) and vocals and kick drum. and sometimes just a general room mic with a kit or guitar amp. we've also talked about how in sessions with a lot of bleed they are very musical sounding. does anyone have a cool method for deciding when to go with a ribbon? maybe some sound clips that feature a great sounding track recorded with a ribbon mic?
