I like the API mic pre's a lot (also the BAE 312 one) and will use those for guitar, but I usually choose first my own custom made Lucas mic pre for guitar. It is based on the Neve original 1073 design (wow, that's a new and novel idea!), but tubes are employed instead of discreet transistors. This gives me the "grain" often associated with a Neve, but also a tube "warmth" (boy, I really hate using this ambiguous, non-specific terminology, but what else is there?) The Lucas has the extra gain stage, but I have found that I don't like that too much, so if the source needs more amplification than the 45 dB of the Lucas' first stage, I will go to something else. I also have a Summit tube mic pre from about '89 or '90 that I have found works well on guitar. It overloads nicely."
