this battery box indeed has bass roll off. it doesn't have switchable positions (i believe it's at 160hz).
i made some recordings with them and they were acceptable. always had to boost the high's in the post prod though.
The guy who´s selling the mics said that it dont have a button for switch the positions...You're right
Don't do it... Squids are the marijuana of taping. The gateway to less time and money in the future.
Do You think that i'll get better results if I tape with my nowadays rig (Sony ECM-DS70P Mic)?
What mic do you recommends to me? I have to have one discrete, because here in Brazil, in almost every venue, they dont acept taping, so I have to Hide the equipament during the concert & when I'm getting In.
The mic that I have (Sony ECM-DS70P) its good, but I'm searching for something better for a Nice price. And maybe, with wires, because my Mic have wires, but dont come with clips
Here goes a pic of the model of my mic:
