Updated now that I've checked them out more closely: These are long scale, but they were cut for a string-through 30" scale bass w/ 4-inline headstock, about 3 wraps/peg. I believe they are mediums, but I don't have a caliper to check. Here's the catch: Tuned the E too high trying to troubleshoot some buzzing and it busted on the post, so the E is short. These should work on a microscale (<30") or something. It's 34" to where it breaks if you want to check your instrument. $3 shipped to anyone who can use them in the L48 or pickup in LA for free.
