The excellent Slovenian guitarist and tech wizard Uroš Barič via his site guitarise.com made this great video on mic comparisons. You can view it on his YouTube to jump to different mics with ease. See the full rundown and specs at Uroš’ post: Ultimate Classical Guitar Microphone Shootout – ep8.
Uros is a great resource for sound, video, and musicianship. He is all about the quality! He also has a label, Baros Records with a recording studio located in Vremska Valley, Slovenia.
