My skills are more in the woodworking and fretwork departments. I can solder well enough but have no great knowledge of circuits. I mostly build and work on acoustics in my spare time, which doesn’t require any electronics knowledge! I’m sure this will come across as a bit thick to many of you!
I’ve just done a refret on a jazz bass, which has had a blend pot added at some point. The owner has asked me to take a look at the circuit while I’m at it. None of the three controls; master volume, blend, master tone, seem to have a very good sweep to them and are a bit on/off. The volume pot is an audio taper, not sure about the tone (don’t know how to measure this).
The circuit doesn’t seem to look like any other diagrams I’ve seen online.
What can I do to improve the taper of the three pots in the circuit?here is the circuit;
I’m not sure of the value of the yellow component as this is tucked in close to the longer one next to it.

Everything else does appear to be wired correctly, so it's either that, just that the pot tapers aren't very good (many modern ones aren't, even from good manufacturers) or that it's plugged into too low-impedance an amp input (eg one designed primarily for active basses), which also messes up the tapers.
