Hey guys, I'm new to the forums, and I just thought I'd say hi before I started in with my questions.
I'm looking to build a small audio amplifier, something that will amplify a signal straight out of a guitar to play through a 3 watt or so speaker. What I want to do is be able to hook it up to a 9V DC power supply, and I can't seem to find a schematic that will allow me to do so, they all need a positive and negative voltage. The one I was looking at primarily was this:

Can anyone help me with the biasing so I don't have to use a negative voltage supply, and so I can run it off of 9 volts, or can someone direct me to a schematic that will do what I want? Thanks in advance.
