I'll add.. when you have more than enough electric guitars
there's plenty of creative fun & inspiration to be had
experimenting/mucking about with substituting wound and unwound strings & gauges in all the 'wrong' places..

Sonic Youth are worth mentioning;
a band I'm not too keen on and my mrs positively can't stand.

A band acclaimed/notorious for multiple song specific 'invented' tunings
in quest of diverse sonic textures.
