Thanks for the giggle here Gary!!! What IS clear is that you said "Good thinking. That works". Enough for me..the rest looks tooooooo much like Algebra!!! (I must not chew gum in class...I must not chew gum in class.........I must pay attention in class......I must NOT let my imagination run wild in class...I must NOT play with the squirrels.) bg

btw....just read your apology above. Just because some of the information posted in here is over my head, does NOT invalidate the info itself. I CAN recognize some GOOD info here and will harvest it IF and WHEN I can accept it as English!!! I'm sure there are others reading who DO understand more than I can now. and even the stuff I don't understand is interesting to read - different approaches and corrections. Some of the posts I want to understand NOW......but haven't even done my homework on the guitar yet. ( Anyone got a straw??) Thank you ALL again!!!
