Short comment on the serial/parallel/single switching: serial is obvious. But if you need a boost, choose single. If slightly different sound, parallel is your friend. I might make an educated guess that two options is a lot, and three just too much.

I would divide this into two: boxes that reproduce directly what's put in, and those with adjustments. DI box can be passive, transformer based, or Phantom/battery operated with or without output transformer (like Countryman Type 85). Which is better is a bit of semantics. I might say that a battery operated is surely a match, especially if your signal is sometimes of very high impedance, like piezo. If you want to include some signal tweaking, then a unit like SansAmp, or nearly any preamp with DI out could be your choice. If money is not an object buy a Jule Monique. Otherwise visit Thomann.de and check which unit is sold in numbers.

Daily issues: - unergonomic long - and even some short - scale basses - long life roundwounds - several sounds from a single instrument (Jamerson to King) - bass fx that do not lose low end (X-over units) - energy efficient amps exist in high power and small form factor, but cabinets on the other hand... bubbling under: - wide freq range pickups - wide freq range cabinets (true FRFR, not PA stuff)

The bass I did metal parts to, has an oak fretboard. Felt very nice.

As you have played many of the tracks, have put them to paper? Any chance you have a library of bass scores?

174 Hz F3 285 Hz close to D4 396 Hz close to G4 417 Hz close to Ab4 432 Hz close to A4 528 Hz close to C5 639 Hz between Eb5 and F5 741 Hz Gb5 852 Hz between Ab5 and A5 963 Hz close to B5 By the way, there are many frequencies that are 111 Hz apart from each other. But scales are not linear... Anything related to health: there's no connection to health that I remember from acoustics lectures, but that kind of scale might cause you some headache.

I can sing, walk, and even play bass. But two or more things together is a no go. M. King can do both, but he's originally a drummer.

What I have heard is that he loved Rotosound, and he used roundwounds, too. Which ones, I have no better understanding. But some comments have pointed out that he hit the strings very hard, because his first strings were flats.

If you want to make the bass a close copy of Louis Johnson's, put flats on.

Composers die and their actions will be forgotten, but good music lives forever. OK, pretty long.

The bass is in the luthier's shop. I have a hunch that I have a meeting with him in the very near future. Aluminium parts still have to be anodized. I will take pictures when we meet.

I remeber playing it in music school long, long ago, but the score is missing from my library. Maybe in some Real book?

Dear Baloney, I think your comment includes the original, although a theoretical question. But magnets are produced in big amounts and the tolerances already dictate the strengths. Magnetizing - which has also tolerances - produces components that are then selected to represent certain specs. A magnet is not ideal, because materials and production methods are not ideal. There's no one magnet that represents all similar sized magnets, except that it's more or less magnetic.

At the moment I think you believe that a certain family, like AlNiCo represents certain "power level", although an AlNiCo magnet can be as weak as a plastic rod. The size does not only dictate the magnet, there are many parametres starting from the materials and the production process. There will be tolerances, too. Magnets are produced in big batches: you can ask what are you after, and the factory can find the right products for you. If you make an order of two magnets that are only slightly different in size, they can be ordered with the same "power level". As I said earlier, Neodymium can be magnetized far weaker than an AlNiCo, or SmCo, or a simple ferrous magnet, although it can be the most powerful of these few families. This depends on the production process and the need. Am I clear enough, do I answer your questions? (The pickup itself seems to be ordinary, although you say it is special made. Do you want to open it up a bit?)

A very rough idea of the cable: 0.5 mm2 = AWG20 => 5 A = 5000 mA Because some diameter is lost in the connections, and the cables will degrade over time in active use, I would suggest using 2 x 0.5 mm2.

You should read about magnetic inductance: when a metal part (string) moves in a magnetic field surrounded by a coil, it creates voltage to the coil. The voltage is dependent on the amount of wire in the coil and magnetic field. Voltage can be increased by making the field more powerful (move the string closer, or use another magnet), or putting more wire to the coil. This has also other effects: a bigger coil reduces the frequency response (EMG has less wire, and has wider response, although faint signal). Very powerful magnet would affect string movement. Coil magnet pickup is a BPF (band pass filter), as it doesn't go down to DC, and is limited up to, say 4 - 5 kHz. Piezos and light based pickups can reach much wider response, but require a bit more complex electronics. This equals higher price, which one certain Leo didn't like.

Yes. Depending on the preamp you may need a suitable cable to the speaker. It would work with an unbalanced plug to XLR cable. Genelec is probably not the cheapest option, but practically any active unit will work.

How about an active speaker? Buy a Genelec. Low vol, wide response...

I am not quite sure, what is @BigRedX after here? I did make an educated guess that the magnets are from the same batch, although they are different in length OR some poles are adjusted to different height and the main magnet is uniform. I would be very much surprised to hear that magnets of different strength would be selected to E, A, D, and G string on any mass produced pickup. But I know that you can buy bigger batches that are of certain strength, because I worked with magnets some years ago.

Put the Chief (or the Grizzly) right after the bass. Not to the loop. Try that first. Then compare the sound in the loop. If your bass has a preamp (a battery powered tone stack), it may be so that the placement of the OD/dist/fuzz can be whatever. The signal that drives the pedal is lo-Z (low impedance) and the signal is practically the same in the pedal chain. But if your bass is so called passive, that fuzzistor of yours may act differently if it is the first after the bass, or deeper in the chain. Do trials, and please comment here later on.

What's that? Looks incredible!

The distance is the key word here. You move the poles further away from the strings, the magnetic field diminishes, and the signal becomes fainter. I was about to write that the sound becomes fainter, but that can be adjusted by amp gain. Make trials to hear the difference in sound.

Buy a Bourns MN 250k or 500k blend pot, and tin it in between the pickups and the vol pot. Done.

Slowly. You can also try Rod Stewart's Da ya think I'm sexy. Bassist (whose name I forget) has very good feel.
