MY TRACKING ROOM....
lol
well, it's a downstairs basement bedroom,
that has been gutted....
i have audimute sound blankets on most of the walls,
with some drywall left exposed in specific places,
that are in line with where i sit to record acoustic instruments.
i can align my mics with the walls to get 'slapback' acoustics,
or i can rotate the whole thing and take the wall right out of the equation.
i have corners treated with combos of hollow rollers and large pieces of foam...
i have aurelex-type angular foam in certain 'hot spots' for high end reflections,
most of this is done strictly by 'line of sight' rules, and using my ears.
mostly,
it's simply sitting close to the mic,
finding exactly the right sets of gains for both my preamps and my compressor....
and mostly, playing cleanly, exactly, with control, and having the mic pickup exactly what it sounds like right at that spot.
i have 3 different condensers that i use,
a ADK Hamburg, a Audio Technica 4033, and a Shure KSM44.
typically, i don't bother with stereo mic setups for acoustics,
i like to make a go at it with only one mic.
i typically point it towards the neck/body joint...
but sometimes i'll shift, using the headphones to dial in my position to the mic, and then i try not to move too much!
LOL again.....
i use either an expensive A Designs Audio MP-1 mic preamp, or a super cheap ART DPS mic preamp (kind of a rack version of the MPA but with a Digital Convertor built into it), and into a DBX MC-6, and into my maudio Audiophile 192 card.
really basic, overall very cheap, works.
