Can you attach a mic boom to that Griffin stand?
Hi Don,
There is no official mic boom attachment accessory for that Griffin stand.
However, we can always use generic microphone clamp to clamp a mic boom arm or goose-neck to the keyboard stand such as this On-Stage TM03 table microphone clamp for grips between 0.625" and 1.625":
On-Stage TM03 Table Microphone Clamp I measured the thickness of the double brace back bar of the Griffin stand (for second tier support) and it is within range of the above mic clamp.
Thanks,
Paul
