Chose the ST1 for my first build with Dark Onyx finish. Two quite different pieces of timber joined just above the pickups probably meant a solid colour might be better but the grain was interesting. A bit of mystery as to what it would look like exactly, but the idea of a black body with the grain highlighted had an appeal. I was fairly sure that the pic of the finished guitar on the dark onyx web page at pitbull was in the wrong place so I was going off the sample colour photo from wudtone.
First pic is out of the box and then the sanding began - repeating the db mantra. Found a place near the neck that was quite shiny, so attacked with a wire brush and sanded some more. Basswood is very easy to work with.
Wetted it down and could not find any glue marks, so went to the first deep colour. Let that dry for a day and repeated. Not as dark as I thought it would be, but the grain was standing out beautifully.
