They both turned out great.
I get what you say about the window between alcohol and water. If I'm blending, I would only use water on all colors. The reason I use the alcohol dye is so they won't blend at all. You could achieve the same you did by cheating a little bit. Stain dark with the alcohol, then as you sand back, go over the entire face and remove just enough so that the figure starts to show, then carefully sand only on the figure, you got to be very careful, because if you get to overzealous you can create dips that will show on your finish product. I did that on that bass, I noticed that the cherry was being sanded out too easily, so once I had the grain the size I wanted, I switched to a small piece of rubber and just sanded on the top of the figure, doing all possible to avoid the grain. That is the reason, if you look closely between the other guitars and the bass, that the grain look like sharp skinny veins on top of the figure. The other guitars look more soft and blended than the bass.
