Re: Using bottom 4 strings of 5 string set on a 4 string bass?

Yeah, that's a good guess. Add that to Jim's calculations, and I think I
have a decent hypotheses.

What you said about "equilibrium" rings true. I had a monster tapewound set
on my Fretless '82 Bullet neck for years. I finally pulled them off and
threw on some Elixirs, and the neck instantly S-curved, while the trussrod
froze. I finally resorted to using a HUGE mechanic's Philips head driver and
torqueing it with vice clamps and a pry bar. Busted the truss rod
completely. oh well...

Like I said, I'm not a fan of 4 on a side tuners, OR 1 piece necks. But like
an English automobile, you take the good with the bad I guess.

So should we add a caveat to the standard AGB "BEAD conversion" thread -
"not recommended for use on Fender style instruments"?

I think the 4 on a side setup had a lot to do with it, but that still
doesn't explain why the neck did NOT warp after all those years under
"higher" tension.

That's true. Here are a couple of guesses. String tension is not
identical across all the strings. In addition to pulling a bow in the
neck, if the tension varies too much from side to side, it could pull an
arc in the neck in the same plane as the body -- "sideways" in relation
to the fingerboard. The change in set-up could have been enough to
upset the equilibrium that had existed in the neck for years. Also,
some basses are just prone to developing bad twists and bends after a
certain number of years. I think it's a slow, steady process that only
becomes evident after it reaches the point where it affects playability.
The dreaded "S" bend in Fender necks is the perfect example of that.
It's what killed my fist Fender I bought brand-new, a '72 Precision.
Your bass may have been on that path, and the change in strings changed
the tension enough that it became evident for the first time. I've
heard it said that truss rods can hang up and stick, and they'll
suddenly release and "spring" the neck to a new shape when strings are
changed. I've seen techs put necks over their knees and give them a
whack, like they're trying to break the neck in two, to release the
truss rod. Maybe your string change was enough to unstick a hung-up rod.

Can't do anything but guess, but I do believe you when you say it warped.
