Adding a tone control to only part of a circuit

[Tuxedo3]

Hey guys, so I have a fairly simple boost circuit i've been working on that utilizes a spdt switch to engage some clipping diodes for some dirt as opposed to just boost. Here's my question, could I add a tone pot to specifically the clipping section? I basically don't want the tone knob to adjust anything when the switch is engaging just the boost circuit, but when you throw the switch to engage the diodes I want the tone to be engaged. I have a schematic drawn up that I can post later but as of right now the diyguitarpedals 10 Minute Boost/Dirt schematic is pretty close. http://www.diyguitarpedals.com.au/shop/boms/10_Min_dirt_&_boost_Schematic.pdf

Put a capacitor in series with a pot in parallel with the diodes.

as said above, most common example I could think of would be the clipping diodes and tone control from the proco rat. basically put that on a switch. nice part is you could mount all of your components on the pot as everything is going to ground.

Should the pot come after the diodes to shape the clipping? Or before to shape the frequencies before they are clipped? Also, i've only read about tone controls almost immediately before the volume control, how would I control the tone knob that is on the switch back to the volume control?

Ignore this, my bad. They will be in parallel.
