I tried to use the search and could not find this. I am wondering what very basic equipment i would need to make those mp3 like some people have on their pages.

I was also wondering if there was a cheap way that I could find something to use were i could record vocals, a backing track then add my guitar to it.

Here is my current gear
ltd m1 guitar, peavey tracer, randall rdx20 watt amp, digitech rp 150.

My understanding is there may be a good way to use the rp150 to record.

I am trying not to spend a fortune on it. Any advice is greatly appreciated.
