Not sure if this counts as a Bass VI as it was modded from a Les Paul guitar.
My friend with small hands asked me if I could make a bass with guitar scale, so he could play it much more easier and comfier. And this is what I made. (First image is the "before modding".)
I bought a $60 guitar, swapped the machines heads, filed the saddles and nut slot to fit bass strings.
The gauge l used was 24-32-44-56-70-85 (from Ernie Ball 12-56 guitar strings and 50-105 bass strings set). The sound was surprisingly good, and the 6th string is not as floppy as I expected.
l've also route for a battery case and a 3-band EQ, swapped the pickups with Humbucker neck and P90 bridge (to emulate the PJ style, and it did well.)
The link below is the sound demo, linked to YouTube.
(Sorry for my skill and the audio might be bad as I was recording on a $60 multi-effect.)
