No worries Robbo.

I tested many different things on builds 1 - 4 but not what other stuff would mix with DT. What I did learn is that Tru Oil does not like water based stuff added and whilst it is obviously more oil based when compared to DT tend to suspect it would react in a similar way.

A cheap way to find out is to buy some small round plastic storage containers from Woolies for about $2 for a pack of 8 and start mixing a few drops of this and that in some to figure out what works and also looks good. Cheap fine paintbrushes can also be purchased in a pack of 10 for small change too. Scrap bit of pine works best for the sample strips as it should be a similar colour to basswood and thus provide a close indication how things might turn out. Of all the additives I experimented with fountain pen ink was the easiest to work with and strongly recommend never using ink pad ink as it tends to have a rather gooey oily state that looks crap straight out of the container being rather dull and lacking depth of colour.

If the budget allows and your up for experimenting with DT you're probably better off sticking with different shades or colours of the stuff or PM/email DB asking him to make up a custom colour as that is what Andy did on his Rosewood coloured Strat which featured in July GOTM.
