Definitely worth messing with the pickups from guitar fetish imo. Another one to get something new out of a disappointing ā1 dimensionalā guitar - sand the thick poly off the neck and top, rub in a bit of pure tung oil, play around with picking position, touch etc after doing this. Metal pick on bass, anyone?
Thereās another hack - you can rewire the tone and volume controls ā50s styleā (look it up)- this subjectively seems to make the tone and volume somewhat unpredictable in their interactions.
This kind of instrument plugged to a āproperā tube amp is hard to describe and sounds like snake oil. But leo fender et al were designing with their ears tweaking combinations of passive pickup and classic amps.
Thereās nothing magic about the old gear, but 50s amp and guitar designs sit in a crazy sweet spot for mod-ing and tweakingā¦
Many happy accidents to be had in this general area - though it is obviously very well trodden ground.
(Sorry that ended up hopelessly off topic for āfuture guitarā, maybe the old designs and more importantly the āears firstā design approach has something useful for the future)
