Please tell me if you have any issues with my layout. TIA

I believe you have something going on with the IC being flipped.

For example in the schematic the 9v connects to pin six. on your layout it is connected to pin 3

The IC on the layout looks 'mirrored' - like the view is from the bottom rather the top of the IC. I think the connections look right based on the location of Pin 1.

Thank you both for your replies.
JoeR, you are correct. The view shown is looking at the solder side.

I think the 220uF output cap is pretty big. usually we talk about nF for guitar and maybe 1 uF for bass or so, if I'm not mistaken.

did you build it and there's a problem or did you want to make sure before commiting?

I have bread boarded it, and it sounds fine to me. I just didn't want to waste an etched PCB that was laid out wrong.

Ahh, I apologize I was not looking close enough.
