...in answer, dunno whether I have perfect pitch or not but my ears have always worked for me over the last 30 odd years. I have seen various people using electronic tuners who have still managed to end up with their instrument horribly out of tune (not that I'm saying that the tuner is faulty, maybe it was nervousness on the part of the operator) which makes me say, what was the point in spending all that money on the damned things? I think as well, while ever you are relying on an electronic tuner you are not developing 'an ear'which I think is important, I'm not saying they are useless, just that you shouldn't be too reliant on them
