I got suprising stellar results from a pretty minimal approach/minimal chain: XY Studio Projects C4s set flat about 8 or so inches from a 1978 Martin D28, through the Apogee mini me set to Soft Limit/Compressor curve 1...the mini me's pres are really clean and transparent, quite appropriate for the job.
It came out really killer sounding, by far the best acoustic sound I've gotten to date! Of course that's a killer guitar too, but had the potential to be extremely boomy with that 30 year old rosewood if I didn't play around with that effer to find the sweetspot...
The player was singing live as well, so I had an MXL V69 setup for that, about 3 feet above the C4s and 2 or so inches closer, upside down and angled slightly back 15?. Solo vocal track will be laid down later...so that will act kind of as a scratch, but the bleed will be nice for depth...
Wait a sec, am I out of the low end theory realm? Should I go back to where I belong?
Seriously though, had to share because we were all really impressed with the quality of the tracks...A/B'ed them to tracks laid down with "8 figure" equipment, and they more than held up...really sounded better. Just my 2 pesos...subjective schmubjective...I think the guitar was the real clincher.
