Sorry, I'm not properly awake yet.
Blindingly obvious Thought has only just struck..

If this is a good excuse to buy a good cheap used guitar...

A 12 string would seem ideal

You can then subtract and add strings back on as often as required
And the bridge should already be fairly well set up.
If you take a course off to go Nashville, it may only need a minor truss tod tweak,
Then good to go...

More strong black tea needed to wake me up mow.
