Man! Did I ever goof! But not really. D'Addario's website has these strings' specs at fitting basses up to 34 inch scale.
Where the main winding steps down, they are about one inch too short of fitting over my Fender Bass' nut.
So, these strings are indeed for medium scale basses. I paid $47 for 3 packs. My loss is another's gain.
$13.50 shipped for a single pack. $26 for a double pack. $38 for all three packs. PAYPAL USA 48
(2 packs are unopened. One pack was opened but never strung. As it was obviously....too short!)
