Help with home recording studio?

Im not sure what you are asking, but Im uming you trying to record your guitars. The best way to get what you want is to mic your guitars. I suggest a Sure SM57 ($100) to mic the amp and you can find a decent Condensor pen mic for your Martin for under 200, check sites like Musiciansfriend.com and sweetwater.com for prices and advice. Just remember that recording is an art form and it could take several ours to get the sounds you want recorded.
