I've used Dylon fabric dyes (which are aniline based, pretty sure) to dye two bodies so far, one alder and one poplar. I just bought it at Wallmart. I did black dye on the poplar body and, though the Dylon works well, dying light wood black is tricky. Some things I read (sorry can't remember where) suggested that straight black dye would look bluish unless yellow and red were laid down first, so that's what I did. I wasn't happy with my results, but finishing is often like that in that you're the one who knows the imperfections and others usually think it looks fine. For me, a bit more practice would give exellent results. You may already be more competent with finishes than me, it's my weak point. Just want to warn you that dying wood black has some difficulties, but that I can also see that if done right, would look really nice.
