Curious why you chose to use the waxed product instead of the dewaxed. I have never used the waxed so I don't really know what advantages there are to using it?

First, just for for clarification, by "alcohol" fender3x (USA) is referring to what we know as methylated spirits. And by methylated spirits, I'm talking about 100% industrial methylated spirits, not the 95% stuff you get at Bunnings or the supermarket. (I have carried on about this in a number of threads)

Waxed vs dewaxed, as used in our pursuits of guitar finishing, the reason for using de-waxed is about compatibility with other finish materials that may go over it. For example is the shellac is used either as wood sealer or to get a bit of colour under another clear coat, it needs to be dewaxed or another material (paint, poly etc) won't adhere to it.
I you never intend to apply anything over the shellac (other than more shellac) there's no reason you can't use a waxed shellac as your finish. However IMO, shellac on its own is not a top choice for a guitar finish for a number of reasons.
