I need to start up little home recording project in order to lay vocal tracks. My friend had an mbox and I've heard the stuff it produced on his demos, I was wondering is an mbox worth the money or if I should wait and get a digi 002. The only mics I have are a B1, sm58, and sm86. (keep in mind this is only for adding vocals to tracks, nothing else). I was also wondering if I should get a small diaphragm mic to pair?
