I just went through a horrific experience with a swamp ash body. Same deal. as it turned out I wasn't real wild about the color and sanded the heck out of it. I agree with everybody else. However, one thing to keep in mind is whether you used alcohol based dye or water. Alcohol doesn't penetrate half as mush as water, thus you may want to start with 220. I did mine with 50/50 water to alcohol and it was very deep. Getting the deep scratches out from the 150 grit was almost as much work as removing the dye itself. Oh keep in mind that getting the original color out of the grain is an interesting task as well. When you think you are good, wipe it down with naptha or mineral spirits. You'll find out that you still have a ways to go. Because the hidden dye will surface. As they say, "sand and repeat" until you are happy.
