My first reaction was to launch into the reasons why I find this kind of religious intrusion problematic. But I think Jeff/ Tinpan are on the right track...... I guess my better "angels" won out (appoligies to Jeff and Tinman who may have never considered themselves to be Angels). Back to guitar questions....

So, can I use a tritone to deduct the long term depreciation of my standard rolling stock ax, if I only own one guitar and I have no dependants?
