No mahogany on the body - stain is Walnut and a little Japan Black. It is showing the colour I was expecting from mahogany in parts though. "Tim Tam brown" isn't a bad description!
There were a few issues with the first coat of neck stain. There's that light spot on the heel (not the fact that it's lighter, but what looks a bit like a glue spot), some darker spots on the side that you can't see, and a light spot on the front of the headstock. Second coat seems to have taken care of those though!
I made a dilute Japan Black to try a burst, but I hated the way it looked on the section I tried, so I loaded a rag with the FW thinner and wiped it off, which seems to have lifted most of it. I'll check the colours again once this neck coat dries, but I reckon it's very close now, and it's also very close to what I had in mind when I started, so hopefully this will mean I'm done with staining.
Waiting for the Tru-Oil to arrive and then I'll have a go at that. I've read conflicting things about how best to apply it, but the one that seems to make the most sense is "do 2-3 coats without sanding, sand smooth at around 1000 grit, then apply many very thin coats sanding lightly between each until it looks how you want it". Does that sound about right? Should I bolt the neck on before I do that or leave them separate?
