1uF should be fine. Are you sure its 1uF and not a fake - incorrectly labelled. If the cap is good and the pot is correctly wired you might have an impedance mismatch with your source. IE the frequency attenuation might be being caused by the volume control interacting with the output cap of your source.

Apogee One is 30 OhmWhat is the output impedance of your source ?
If everything is OK then it might be down to the rest of the set-up. The B1 is pretty transparent so wont affect the frequency response of the rest of the set-up. Try taking the B1 out of the system by simply connecting the wiper of the volume pot to the power amplifier.

Ok will do this
In my B1 I used DIY boards derived from the PCB layouts on the Pass DIY site. Even then I found discrepancies. I would check your boards very carefully by reverse engineering the schematics.
Did this already but will do it again,

Without the B1 pot is working fine
Ok, it looks like I found a msitake on this PCB from the other forum. There is one cap with 0,1uF called C4. This one is not in the original B1…
If I take this off my pot behaves normal
Thanks alot for your input!

An externally hosted image should be here but it was not working when we last tested it.
But its funny anyeay, cause the guy from the other forum shows a pic where this
caps are also installed…

But he didnt put in a pot...
