The stain is a water-based stain from Stewart-Macdonald. I took a few drops of tobacco brown, and thinned with a few drops of water at a time it till I was happy with the tone. Then I brushed it on with a stiff-bristled brush. After it was dry, I used Clou Antique furniture paste wax applied with a cotton rag. And then polished it on the buffing machine.
You can use the stains for staining all kinds of wood. For a guitar body or neck you need to mix it till you're happy with the tone ( try on scraps from the same wood until you're happy with the tone ), and then when it's finished, either wax it, or spray with clear laquer.
In this book:
https://www.stewmac.com/How-To/Books/Guitar_Finishing_Step-By-Step.html are recipies for all the guitar colour schemes known to man, including the classic sunbursts from Gibson etc. And Stewmac has a set of 10 thinneable stains so you can mix any tone you like. They last forever, I bought mine ten years ago, and you can't even see that the level in the bottles has sunk, as you only need two or three drops for each job.
