I too have been looking for some kind of portable mic boom device which could somehow clamp to my keyboard (PSR2000). Nobby, it's disappointing to hear that you are getting feedback (rumbling) thru the internal speakers. Can you explain what type of clamping device you're using? How and where are you clamping the device to the keyboard? Is there rubber (or sound dampening material) in the clamping device to keep the sound from transmitting from the boom to the keyboard? How about the mic boom itself? Is this a specially designed portable mic boom unit? Please provide details in your setup.

I somehow remember a keyboard (a few years back) which included a mic boom holder built into the keyboard itself. Can someone here possibly refresh my memory about this? This sure would be a great built in feature for our arranger keyboards. Until then, it would be great to figure out a way to attach some kind of portable mic boom to our arranger keyboards, making one less piece of equipment to have to transport to the gig. - Scott
