I have only used dewaxed. That you can thin for sure. Not sure about the waxed. People thin the dewaxed all the time. I looked at some woodworking sites that recommend thinning waxed with alcohol. Even Bullseye. They also recommend NOT using anything but alcohol though.
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.

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.

We had very little time for the complete project and based on some Youtube videos Shellac looked promising as it dried fast and was easy to work with.
On selecting the product we wanted an Amber tint to the guitar and that was only available as waxed. I believe their clear shellac comes as waxed or de-waxed.
So we didn't have a de-waxed option, but also we didn't know the pros/cons of each either at that time.
