I am micing an acoustic guitar with 2 condensor mics(not the greatest, but fair), using an Art Tps II 2 channel preamp, and a korg D888. In the past I felt I have recorded with the levels too loud, not peaking, but with the gain high enough that it creates a guitar tone that is far from what I desire. I have found at lower levels the tone is more natural and warmer. My question is how, low is too low? It looks like on the recording I did today the levels are mostly between -30db and -20db with a couple spots getting as loud as -13db and as quiet as -40. When mixing and mastering will I be able to get the levels up high enough to make for a satisfying listen for most people?
