Some basses have a much smaller tuner capstans and this puts too much strain on the unsilked portion that inevitably becomes wrapped around the tuner on shorter scales.
Dammit, I shouldn’t have posted earlier as this prompted me to pull the HB out of the cupboard and give it a play. Now I’m looking at that EMG GZR PJ set! Fortunately, it’s on back order, so nothing will happen in the short term.
