As long as we're on this subject, I'd love to hear from ya'll on this one:  
 When replacing bass strings in the field and putting that final twist in 
the string, I've always relied on my Clark Kent vision to look at the end of 
the winding to reveal which direction the copper winding is going.   ... 
Last week, I replaced an uber-fine bass string on a CP-70 and it's winding 
direction wasn't immediately obvious.   I put on reading glasses, still 
questionable.   I got a magnifying glass and after a couple of minutes finally 
determined the direction.   It was NOT, as it happens, the same direction as the 
original strings on this beast.

SO... I humbly ask my colleagues -- short of lugging around your handy 
electron microscope, as was needed in this case -- do you have any tricks for 
determining coil direction?   Is there a different method to each 
manufacturers madness?   (In this case, it was Mapes.)

Thanks, ya'll,
Jim Wilson
