I have about six favorite vocal mics that, for vocals, I plug into one of three different awesome preamps, then straight into the converters. Later, when I compress, I have about three favorite compressors to choose from. Every one of these chains "rocks".
Although I'm fairly satisfied with my vocal mics and preamps, and usually satisfied with my compressors, I wouldn't mind having a couple more flavors of compression. Or a nice EQ. Being a slut and all.
