    Very 'cool' effect mic

    Posted by Cam S on Aug 3rd 2014

    This mic, man, it has something real "cool" about it, when you listen to an instrument mic'd through this, there's a certain kind of "familiarity" in the sound, it's low-fi, crappy sound but - the unusual tone of the mic makes it a quick favorite to me.
    We recorded strummed and fingerstyle playing on acoustic guitar, vocals and harmonica.
    We thought the strumming sounded real bad, but the rest (especially the fingerstyle playing) was excellent!

    No issues ordering through Frontend, order was well packaged and arrived in the expected time-frame.

    Very cool mics

    These mics rock! They are obviously good on Harmonica, but they are one of my favorite "special effect" mics for vocals. They distort really cool.
