I recently got some advice on a preamp for my mic. I was told to get a lunchbox 6b and a API 212L mic pre, but when Vintageking sent me both it didn't look like they were compatable. Did I get bad advice and waste my money or am I not looking at this right? Do I need a 512 or will the 212 work? If the 212 works, can someone explain to me how it fits in the Lunchbox 6b? Any help would be appreciated, thank you.
