Actually, DJL's reply to my question has me thinking.
I've tried a Rode NT1000 and a Marshall V67 to record my acoustic guitar.
The Marshall I didn't like at all with my particular guitar. The sound was kind of murky, dead and undetailed. The Rode was much better, but it did give a kind of fat sound that was OK for solo voice and acoustic guitar.
In fact, I was surpised at the sound I got from the Rode, since makes my vocals sound a little more trebly than I would expect, but my guitar a little less trebly than I'd expect - maybe it has to do with placement.
In any case, I see that some people prefer LDCs for
acoustic guitar and some prefer SDCs.
But is it the case that LDCs might be better for sparse arrangements where you want the acoustic to be strongly present than SDCs, and that SDCs are better in a busier mix?
Or is it more complicated than this?
