I don't know if a pop filter would defeat the purpose of a human beatbox here but it would be worth a try...

OK, I have never recorded such an artist, but here's what I'm thinking. You need to let him hold the SM58 (actually, ask him to bring his favorite mic) like he usually does, becuase the plosives created by that interaction are very important in the sound.

Also, I would set up a large diaphragm condenser 12-18 inches away (asking him to keep his head still while he records) so you have some clean signal to work with as well.

Then it's just a matter of engineering the best mix.

i'd say f*** the clean signal and stay with the 58.....it's part of the sound.....

and to ask a beatboxer to hold his head still would compromise his work....

Then put the LD in omni position 12-18 inches away and record that. If you don't need it a mix you can just delete the track.

Saftey first!

as a refrance the best human beat bow sound ive ever heard was no that new bjork album.

Tell him to rent or bring his preferred mic. If he's all that, he won't have any problem doing this.

Then, like the others, set up some omni condenser away from him to pick up a supporting track to mix in later.

I would tell him to go with a Shure dynamic if he wants to try and destroy a mic with his talents. Good luck trying to wreck a Shure. They dunk those things in buckets of water and throw them down stairs to test them.

I tried recording a beatbox one time with a Studio Projects C1 and the result was horrible. I think the guy was like 12-20" away...anyway...I probably should have gone with the dynamic hand held thing. Oh well...
