Hello, HoboSage,
first of all thank you for advice! (about improving my current guitar). I`ll search about it.
While working with another musicians and communicating with their producer and discussing things we came to conclusion it ll be really better to change guitar to electro-acoustic. I can record my voice without noise I have about 5 mics)), one is professional and others are simple. I have Steinberg cubase 5 that I dont use actually as it quite complicated even for professional musicians (it was adviced by professionals to use smth simplier at least for the first time).
And, yes, my room is ordinary one)) I dont have studio cabinet yet, unfortunately. So the easiest way is to buy guitar that can connect to pc directly.
But I ll search what you`d recommended, maybe it can be a solution as well...
