Oh! Good job finding that! Those resistors are quite different in value (14k ohms vs. 1 million ohms)! Yes, 14k as R1 in the input would have rolled off quite a bit of high frequencies.
I’m really glad to hear it’s working properly now.
Once again, good job finding those resistors, I probably wouldn’t have thought to look in that direction.
Enjoy your Quaverato!
Take care.
