I have a like-new Audio-Technica clip on microphone that I haven't been using. It works great, sounds great, and looks good on the bass. The gooseneck is the right length for clipping onto the bridge adjuster and its very unobtrusive when mounted. I used it a few times, but it seems that my gigs are just too loud to use a microphone. This is a complete, ready to go unit and includes the power pack. The power pack on this model runs on Phantom power or 9v and has a switcheable high pass filter on it. Connects to a standard XLR cable.

How about $75 shipped to lower 48?
