IMHO
Its the scale.
A Jag feels like a chicks guitar to me.
I still own a Jag/a Jag bass and a Jazzmaster guit,
(got all three used back in 1976 for $300)
and all those tone controls while a good idea at the time,
don’t really give you the range of options one would think.
I don’t believe the transistor tech was
advanced enough back in those days but at least they tried.
All those knobs and switches did make those axes look kool and futuristic.
And since your post, I pulled them out to check and they still do.
