Fancy elctronic tuners? They're a bit like those awful television machines - nasty new fangled inventions! It's a pity someone can't ask a simple question without getting railed at by someone who thinks "being blunt" is necessarily a virtue. I don't suppose your son will be playing for much longer if that's all the encouragement he gets. Do you call hime "fucking inept" as well? Actually, you were just repeating what the second post in this thread says "Have confidence - if it sounds okay to you - its probably okay!" although the weelittledrummer put it a tad more politely and in fewer words. I've always found a polite turn of phrase and a little ecouragement produces better results than bombastic bullying.
