Hey Folks.
The known problem:
You do live-acts, are busy playing and filtering the gear, and you are using a vocorder or voice-transformer without a free hand or the ability to raise your head to the mic all the time.
So, who of you has experience with headset- oder neck-microphones?
What do you recommend?
(I'm not looking for a home-production-thing, but for one for real live-acts with a fucking loud music level all around the club... so mind the acoustic feedback-issue, please!) 
Greetinx from Berlin,
Timo aka Takter.
