That's a very interesting observation. It now makes me question, what company could be making bass roundwounds at the time?Danelectro was basically an experiment in using the cheapest components known to mankind at the time to make guitars and basses, and a very successful one for a while. Wouldn't surprise me if Mr. Daniel bought bags of defective strings for pennies on the dollar. Don't know who made the strings they used, but I could see a run of the same size string having similar defects.
I think if tape existed of those other takes, they'd be out there. But more likely, they recorded over the old takes that weren't completed. And as far as trusting Entwistle's recollections, he did drink and do a lot of drugs.
That's a long way to go to say I'm clueless, but there you go.
That makes a lot of sense as far as having to buy a new bass each time, but I'm still baffled they would break despite the low the tension. Compare tension on a standard gauge set on a 34" scale vs 40-80 on a 29.5" scale:The Dano strngs back then were probably about 40-80 gauge (the La Bella set was 42-83 until about this year), so it was completely normal to break them. The problem is that there were no short-scale strings light enough to fit on those basses back then, so He had to buy another bass just for the strings.
The tension on the Dano would be about as much as on the standard bass and strings but down tuned 6 half steps to B standard, I just don't see them breaking. So my guess now is that the strings were just the cheapest ones the company could get away with and stay together until you got the bass home. They were so bad they came with post-warranty self destruct!
