is it muddy at all gain ranges? That's really weird. I can't see all your values but they look fine from here. That's the opposite of what it should be doing lol
My first troubleshooting step once a pedal is getting power and passing signal is always to verify all the component values.
You mentioned you have a bass-klon in your build queue - the components involved in that mod could be a logical place to start if you're getting too much bass in this one. I spot checked some of the film caps where I could see the printed values and didn't catch any mistakes. Check the rest though.
I could see an accidental swap of C16 and C22 (47u and 4u7) giving you trouble.
