I think all GHS short scale sets are 32.75".
Based on the 30" basses I own I think we can rule out Pyramid, LaBella and Thomastik short scale sets too. All of them have the windings VERY close to the tuning pegs on regular 30" short scale basses. All of them seem to have slightly above 32" winding length. Thomastik even a bit longer. Many short scale sets are designed to fit short scale basses with short tail pieces too which means they are actually more like medium scale winding length. And the short scale strings designed for basses with longer tailpieces are obviously even worse...
Not sure about Rotosound but their short scale strings are very, very poor IMO so not really worth investigating.
D'Addario Chromes are 30" I think (not 100% sure). Probably as close as it gets with regular short scale strings. Other D'Addario short scale sets seem to be 32".
LaBella seems to make sets for all kinds of basses, at least the Deep Talkin Flats. They HAVE to as these strings will break if the windings are strung through body or wrapped around the tuning pegs. I wouldn't be surprised if they came up with something special for mikro scale basses... But then again, maybe not. It's a very small niche unless mikro scale basses become a lot more popular. And not everyone wants flats.
Well I guess they forgot that coating on my Cort manufactured Squier Bass VI that I purchased recently and oiled last week then. I've never seen a fretbord soaking up oil that fast. 100% definitely no coating on that fretboard. And the laurel looked much nice afterwards. Practically glowing compared to before I oiled it.
