Hi. Thanks for the replies..
Reasoning.. firstly, I want to install a "kill switch" as i often use this on another bass I have. I realise I could do this with my current set up, but removing a tone/vol pot would free up space. A single volume pot would give me the option to bring volume up and down in a live situation ( think effects wise, not just for stage level ) which cant be done with a pair of volume pots.
I could get a foot volume pedal, but I would still like a kill switch so thought this might be a viable option.
