O.K. sound wizards, gurus etc. I have no recording gear at all so would like to get up and running as cheap as possible but with decent quality. I was looking at something like the Rode NT-USB.

I want to be able to do the following:

Record guitar out of an amp.
Record Violin and acoustic guitar.
Record brass instruments.
Record speech as I'm toying with the idea of doing a YouTube build series for one of my future builds if people would be interested.

Video at this stage I'll probably just use my Nikon D3100 (Full HD @ 24fps) or pick up a second hand Go-Pro.

Hit me with your suggestions.
