If that line selector had a X-over... would have to buy three.

A two way has two threads at the opposite ends, and requires very little turning. A 30 degree turn would equal 60 degrees in a one way unit. How did I find this, you already know...

KMA Tyler. On a big side, but very functional. Iron Ether Divaricator is similar, but a hard to get unit. Rolls has some unit, which code I have forgotten.

"Other premium features include... strap and papers..." Now that's what I call premium! I do not understand the hype FMI is trying to include into their basic basses, except from marketing and higher price perspective. After all, Sadowsky et al. are in the high end J market with well thought concepts.

So sorry, thanks for the note, I mixed the terms. Hardening is the right one. Play it again, Sam: "When the metal is bent, it is cold hardened. Hardening changes the metal so that it becomes harder and brittle. After bending the string a couple of times, the bent place is so hard that it breaks easily. Just like the paper clip which @Cato described."

Find a cozy place, get your blanket, and read his definitive article here:

Yes, if the wattage is enough. This one says 45 W which isn't a lot, only 400 mA. If the unit's consumption is low, that still may be enough. Check the effect's specs.

...and need equipment like this: https://www.thecablecooker.com/ Definitely a must!

This is not a bolt-on, or a neck through, but something like a neck through bridge bass. Interesting instrument, I think that Patrick Eggle did something slightly similar. https://www.linkedin.com/pulse/sd-curlee-history-scott-olson

String spacing of the 5?

Grover wavy tuners (actually there are two models: bent and molded) would fit, but they are really rare. That pick-up cover is terrible. Someone sure has measurements of the original, and some company can laser-cut a new one to you. Bridge looks a bit modern, but if it is functional (fine tuning isn't?), could it be modified slightly? After all, all adjustments you need to do with new strings anyway. Mojo? That's another word for dirt. Just clean the bass. But heritage, your bass already has an interesting, even enviable history. Keep it rockin'.

But this neck is pretty new, like late 90's or newer according to the logo. In the beginning of the 90's the text included the word Graphite, too.

MXR Bass comp is also available as Studio comp. The same unit, only different graphics. Spectracomp is most likely your thing. I have Hyper gravity (several, to be honest) which was sold for g-word, but is essentially a Spectra with four pots instead of one. It certainly isn't bass specific. Sound on Sound has good articles about compression, and www.ovnilab.com is a must to anyone about to buy a unit.

I have M80 single and double. Pretty good to carry, but hits your thigs. Running is practically impossible. Double is very heavy even with light weight instruments. It is still the most practical way to carry two basses.

When the metal is bent, it is cold tempered (hardened). Tempering changes the metal so that it becomes harder and brittle. After bending the string a couple of times, the bent place is so hard that it breaks easily. Just like the paper clip which @Cato described. The thickness of a string is not that important, if only the tension is low enough, the core will withstand the forces. Winding is affecting the weight of the string.

After installation, do measure the set in the listening place, and do required corrections. You can get some results with a phone and some RTA app. Accurate systems cost quite a lot, but even a phone can find worst issues.

Type MN has two tracks starting from the centre, not the ends. Therefore the centre is a no load situation. My favourite is still Noll Mixpot, because it is no load for both pickups through the whole adjustment area.

For those who don't know, Bourns makes these blend pots: 250k MN, and 500k MN.

No. Active material, tritium, has a lifetime of 12.5 years. Modern inactive materials are functional for a longer time, like decades, although they may degrade slightly over time. I have seen products that have been up to 60 years old that work just fine. Older zinc sulphite materials are still functional, but they have never been very good compared to these newer Sr aluminate mixtures. You buy any better watch, and the hands are printed with (Super-) Luminova. Watch industry uses mostly inactive materials, because they last so long. There are few companies like Traser that likes to use tritium tubes, but that's a gimmick. You can buy gun sights with tritium tubes (Trijicon, Meprolight...), but again, who really needs them? You need a longer glow, you just mix more powder to the lacquer. Maier's pages are a chore, but if you are active enough (joke!), and understand some German, you may find some interesting data there. Some of it is visible and hidden at the same time. https://www.leuchtfarben.de/

I measured a bartolini set years ago, and I think - if I remember correctly - that anything beyond 4 kHz was more or less meaningless. Piezos are a another story.

By the way, how wide is the frequency response of this "wide range" pickup?

Exactly. I worked with magnets for several years. Material does not create anything else than just a field. The shape can affect the field, but not the material itself. Material can dictate the maximum field possible. Some basic ferrite magnets are weak at their best, while Sm-Co, and Nd magnets can be very powerful. BUT if any very dense material is poorly magnetized, even a potentially powerful material can be very weak. Some people tend to think that any set of letters equal the power of the material, the magnet. This definitely is NOT the case. Without a decent unit, measuring magnets is hard. Without some knowledge on measuring magnets, getting decent results is complicated. Without finding a feasible place to measure magnets, well, you get my point. Even surroundings play an important part of the equation. Maybe one reason in believing to materials is the complexity. Measuring equipment is expensive and rare. The field changes drastically, when minuscule changes are done. The interaction between a pickup, string, and the finger/pick that moves the string seems to be magical. (Which is actually true, when I look at any master player.) But everything is about plain physics mixed with some materials.

Try GHS contact core super steels. Blue package.

A piccolo set? Use a X-over and you can tweak any effect far beyond usable levels without losing the low end.
