The audio technica mike is a great route to go. I've played with a few guys now who love them and we seem to have very few problems on stage.

I once used Blair's condensor mic. It was a fast change from one accordion to the next. Can't remember if it had an on/off switch or not. Wasn't bad at all, but as someone mentioned the cords are about as thick as those ya find on ear buds (thin).

But unless I'm wrong (help me out here), I believe you have to have a phantom power source (yes/no ?).

What I have, is the ole snap on shure, round ball with that black wind sock doo dad on the inside .. and the toggle on/off mounted on a funky looking chunk of aluminum plate ... oh yeah, it works fine for what little I use it. It's a tone monster through that 4x10 hot rod deville (which is pristine, cause I very rarely ever use it).
Down side? I don't have it in a wireless config. so that ya wind up with a long ole cord and have to avoid tripping over it.

What's the word on the best wireless arrangement?
suggestions?

Strangest ( perhaps a bad choice of words, rather most deversified set up sounds much better) I have seen was a dual set up on an accordion: Squeezer Larry Tonkin, had both external and internal on a single 10 button accordion... If I am not mistaken it may have been set up by Dana Mandell... if so, congrats Dana, it was a very clean looking arrangement with the external done up on plexiglass (as I recall)... it was a dual set up to be sure or is that shure(?).

I use a wireless for both my external and internal micing. The samson AX-1 transmitter does a nice job.

Here it is attached to both an internal and external (old school) mic.

Man alive, what a great forum! Many thanks to all of you for the wealth of solutions! And that includes Cory who e-mailed me directly. Got to read all this two or three times and print it out, cause alot of the product nomenclature is Greek to me now, but I guess when you start to get into it, the various types of mics will gel in my mind. Got to visit one of the local music stores and talk to the sound guys.
Again, many thanks.
