For real, none of his “nicer” basses sound better than that old Washburn.
From what I have heard, Jamerson’s Funk Machine had crap action too.
Yer bass sounds great, Doc. I think folk put a little too much emphasis on gear and its cost, and on low action. I think intent of the player and HIS belief in the gear he uses is far more important than the amount paid or name on the headstock. Yamaha basses are built exceedingly well at all price points. I also gave up a very high end, well respected fretless 5 for my current G&L M2500 fretless. For my style and tonal goals, the G&L is simply better. I'm not a flatwound fan. I can appreciate the vibe, but rounds are where I find the tones I am looking for. Steel rounds, even..
As far as action; Jamerson, Miller, Will Lee, Kumalo and many other heroes of mine, plus upright bassists, and I believe, Jaco himself, ran action far higher than folk are willing to believe today. Strings vibrate in an elliptical pattern similar to a planet's orbit. Gotta have enuff room under them to fully vibrate. You get more projection of a string into the pickup, thus more sound. I run my fretless action fairly high for this reason. My fretted action, too. I have no issues getting sustain an mwah outta my basses this way. And my hands adapted, they don't get sore. Plus, fewer marks on my board, in general, vs lowish action.
Each of us is our own worst critic. Each of us, tho, has our own thing to contribute to the world of tone. Don't critique away yer uniqueness, Doc. Own it. That Yamaha sounds fantastic. And, a new set of strings can fundamentally change the tone of any instrument. And strings are far cheaper than a new bass. Especially today. I keep a few sets around for differing moods. I may not like flats, but the folk that hire me sometimes do. So I keep sets for those occasions.
