I record a lot of acoustic guitar in my home studio. I currently switch between an AT4040 and an SM57. The 57 sounds, well, like a 57 - a bit chunky for guitar. The AT4040 has a slight kick in the low mids that make my guitar and mandolin sound a bit boxy. I usually have to EQ it out. So, I'm looking for an additional mic for acoustic guitar/mandolin/fiddle mic'ing. I'm also interested in getting a new match pair of condensers and was gravitating towards the C4s. So, my obvious question is ... can I make this a good dual purpose purchase? Are SP C4s good for mic'ing acoustic guitars and such? How do they sound? Bright? Warm? Tinny? Full? Flat? Boosted in any frequency(ies)? Thanks! Btw, how's the Kel HM-1 compare on acoustic guitar?
