I've been in the process of putting together some recording gear in my music room for the purpose of recording all of the sessions that go on in there, and possibly making some (I hope) reasonably good quality duo recordings. The duo formats I'll be recording are DB/Piano and DB/Archtop guitar. Right now I'm using a minidisc 4 track, and I'm happy with that part....but I know that mics are the most important part of the signal chain, and I can't seem to find very many resources that I can trust on the issue, since acoustic instrument recording seems to be a lost art these days. Online, I've visited SOS in the UK and a couple of other recording sites, but it seems that most of those guys are recording mostly electronic based music. The suggestions I've gotten so far that are in my price range (roughly $500 for a pair) are for the following mics: RODE NT1, RODE NT3, and AKG C1000. I know that large diaphragm mikes are best for vocals, but I have no idea what would be best for DB and piano in this price range. Any suggestions about equipment and/or resources to research this issue would be greatly appreciated. BTW, I'm getting a great sound direct into the board with my Trinity mic for the DB, but would like to double mic in some cases.
