Shure mx183 for an accordion


from Butte, MT

Comments about Shure MX183 Microflex Lavalier Microphone:

Too hot. I mounted it inside my small sized accordion. When I pulled out on the bellows it sounded fine, but when I pushed the bellows it broke up real bad. Like when someone yells into a crappy microphone. It is a good microphone, but not for this application. The Shure sm11 works tons better for the job.
