50-EDD Fretboard is based on the formula (Scale_Length/(2^(x/50))). Being more useful for your fingers, is recommendable a Short Bass Scale Length (818mm [32.2"]) for this 'golden cat'. Maybe for a first instance with it, a employment of the (Cliché ;) 2L3s Dot-Guide :

For the fretboard, that is the 13:8 proportion, 13 8 8 8 13, but not uniquely, a second form for dotting approaches in better way the extense fretting over the fingerboard :
