So, I ordered this opamp called the MCP602 on a recommendation. The idea was to run it on the arduino 0-5v power, amplifying my guitar (AC 300mv max), and then reading the output with the arduino ADC. I posted my circuit image below, as well as the simulation output image. Unfortunately the MCP602…

Op amp woes.

Your signal ground needs to be something like 2.5V

Thanks for your input, but I'm more interested in why the simulation does not reflect the offset result I'm getting in my real life circuit.
