Bosstone diode/volume switch

Working on a Jordan Bosstone at the moment, and I love the sound both with and without diodes.  I'm planning on building it with the diodes footswitchable.  I also want to build in a second output volume control which will allow me to even out the levels when switching on the fly because of the large volume boost without the diodes.

I was planning on using a 3PDT switch for the switching to A, insert/remove the diodes, B, switch to the other volume control, and C, switch LEDs or between colors of a dual color LED.  The only place I'm shakey is with the volume pots.  Is there any reason why I would run into impedance issues, or anything else I'm unaware of, if I set it up thus:  Running the output of the circuit into the center lug on one of the poles, and then from the switched lugs into two pots set up as normal volume control voltage dividers... it seems like having the other pot connected to the output all the time might be an issue.  If this is the case, can anyone direct me to a possible solution?

Thanks!

I dont see any problem.  In any circuit with a volume pot at the end there is a resistance to ground (based on how large a value the pot is) that effects the impedance.  In this instance the resistance will be about half of what it usually is.  If you're concerned you could use volume pots at double the value, but I don't think it will matter.
