I find this thesis preposterous. "The iconic Smith tone simply won't work with a wall of huge guitars..."No reason a KS can't do that style - how well is up for debate. An experienced ear can tell that the iconic Smith tone simply won't work with a wall of huge guitars and even bigger drums. It's voiced and intended for club dates, Fusion, and Jazz, and by association will work well in R+B and Urban Gospel where the Smith mark has found its home. The brand just never caught the imaginations of the players doing Hard Rock over the last few decades. I can't recall any popular and/or nationally known act where the bassist used a Smith, live or on record.
Boutique basses were not unheard or unseen in those times, but were rare. Smith, however, was strangely absent. Lots of MTV bands were big on product endorsement and manufacturers were big on being seen, because being seen on TV turns into sales. Ken Smith had little to no interest in that aspect of the business, but he can afford not to be.
These days, more boutiques are prevalent (i.e. Dingwall). It also has to be said that Ken simply wouldn't be receptive or kind to today's Heavy Rock practitioners if and when they attempted to engage with him. We laughed him off and refused to do business with him 25 years ago, but today's kids simply will not have that.
What???
Plug it into the right dirt pedal and a dimed SVT plugged into an 8x10 fridge and I'm certain (having owned one) that you'd be dead wrong.
