Just a plain plank of khaya? Both hond and afr mahog are considered superior luthier tone woods, to imply that one is superior to the other is just wrong - well unless your in marketing and trying to focus on minor differences to rationalize a price difference. I agree that hond quality is much more consistent (density, figure, color) than afr - primarily due to the consistent growth environment for the hond. However, a superior piece of afr is just as toneful as a superior piece of hond. Manufacturers such as Carvin use hond for all their mahog guitars including their low end products. Others such as Collings simply state mahog for their tone wood. I read this to mean that either hond or afr is used in the manufacture of Collings guitars depending upon what is available, while Carvin is trying to imply something special when in fact they know there is little difference when quality materials are used. The reason I am led to suspect that is the case with the Tok is because I have opened up my 230 and the bare wood has the brown coloration normally associated with hond.
A disclaimer, this is just my opinion of course and I do not mean to be argumentative. As long as it is not luan or holes drilled in the lower bout (ala Gibson's current low end LPs) then I am ok with either one. That said the discussion of mahog does not explain the price difference asked in the original question.
