Yeah, the "chasing the tone" thing can get a bit tiring. In the end you just have to make one work for you (or several). I can honestly say that with all the Roscoe basses that I've owned (ashamed to type that number these days) none of them sounded bad. Yeah, there were a few that were special in the way that they sounded, played or looked but I could have gigged with any of them. And I've only had one that had issues that absolutely had to be corrected. But was it fun getting to try all of those various configurations or Roscoes?
Well heck yeah!
And in the end, when all the smoke cleared, I ended up with exactly what I always said that I wanted, a fretted Roscoe 5 and a fretless Roscoe 5. And whatever those can't do I supplement them with a few basses from other builders that do that well. And IMO there's no shame in that.
In the end, they're nothing but tools of the trade.
