Effects of Inductors Coupling? Answered

This is a follow up post from this thread >> https://www.instructables.com/community/Guitar-Wah-Wah-Pedal-Help/
(It was about how to fix my Wah-Wah guitar pedal, it turns out the Inductor was not working, so I replaced it)

I replaced a broken 500mh INDUCTOR in my guitar pedal with a new one. It works now.

However, I am planning on keeping the broken inductor in my wah wah pedal (because it yielded a cool volume pedal sound).

I want to rig up the circuit so that I can switch from from the GOOD conductor to the BAD conductor.

My questions are:
Will there be any major effects from having two inductors coupling?
Should I be wary of the 'winding' of the coils? If so, what should I do in order to be consistent with the winding?

And out of curiosity, how could I rig this up? 

Here is the schematic >> http://www.voxamps.com/downloads/circuits/wahwah93.jpg
500mh Inductor = L1

I have 3 terminal DPST switch.

This is how I imagine rigging it up:
I'm thinking of having wires from the inductor terminals on the PCB wired to a terminal on the SWITCH, then to the INDUCTOR, and then back to the PCB. The same follows for the other (bad) inductor.

If this is not clear, please let me know, or feel free to post a better way to rig this up.

In summary for this last question
How could I rig this circuit to switch between two inductors?

If the inductor you replaced was broken, it's either shorted or an open circuit. Test it with an ohmmeter. You don't need the broken inductor to replicate either of those conditions.

You can achieve the same effect with a switch to cut the connection to the new inductor, or to bridge it.
