VocalBoothToGo is a great website to check out if you’re looking for vocal booths you can take on the road with you. Once you’re in the thick of things, you’re really going to need some kind of a travel rig. I happen to own one of these and really love it. For more information on how it works, check out this handy video on how everything in the Carry On Vocal Booth Kit fits together.
If you’re needing other voices, feel free to email me with your requirements. I’ll speak with people I know to be extremely talented, reliable and quick and will either get back to you myself or have them contact you directly (whichever you prefer).
