I've got a small scale length guitar made out of a solid piece of Queensland Maple... a "hippy" family made them locally and used to play them at the local markets.. running through 12V car cassettes with a jack wired to the two tape head wires...
I've got a similar small bass to match...
the scale length is around 19 1/2 " or 500mm.. with a 1 5/8"nut.... I used to have it tuned to standard no worries, not sloppy at all....... or sometimes open/dropD for slide/metal.etc... I took the old "ricka looking " PU out to try in a normal guitar....
this little thing ripped through a jcm marshall stack... I took it to a party once and let the band guitarist try it out... he used it on a few tunes...
I'll get it back together soon, you need small fingers to play 6 strings on it... I might make it a 5 string...open G machine,.
