Frank,
You are so right, I put an oscilloscope on my guitar output and was so surprised at seeing 2V p-p on a hard strum! so much higher than light picking. I will probably make the pre post amps adjustable. I knew I would be learning on this project and I am sure getting that in spades.

Re: 3.3V output
Awesome, only looking for 50mA probably less.

Input amplitude
Hi Frank. I followed the reference design in the G01 datasheet then added all of my circuitry around that. Reviewing the schematic before layout I see that the guitar signal is going to the FV1 with a gain of 1 so it's quite a small signal. If the FV1 has a Input p-p max of 3v wouldn't the A/d yield...

3.3V output
I see 3.3V coming out of the module on pin 6. Can I know how many mA are available on this pin? I wouldn't mind saving a regulator if I can power some small circuitry with that source.
