I will be using my H4 primarily to record acoustic guitar playing solo fingerstyle arrangements. For the most part I will be using the built-in stereo mics on the H4. For those of you doing similar type recording . . . my question is: are you getting better results just using the built-in stereo mics in their default (no mics modeling module setting) . . or are you getting better results with one of the four mic model modules (SM57 - MD421 - U87 - C414)? Thanks for your input.
