I want to build my son a scaled-down P-bass, he's only seven but showing a great interest in music now. I have some questions for others who have built mini basses. 1) Can you source a suitable bridge with closer string spacing to suit the scaled down size of the bass? 2) Pickups & string spacing - same as above 3) 1/2 size would give a 17" scale, 3/4 size would be 25.5", ideally I reckon a 2/3 size would be cool, 22.6". Can you get an EADG tuning to fit with this small scale? Or do people go for something like an ADGC?
