    I've always found the B string to be quieter than all the other strings on the bass (only ever owned 34" scale), is there an accepted way to fix that? 

    Some things may (or not) help:

    - string choice (do several trials*)

    - pickup height adjustments

    - bridge adjustments (in connection with the previous point)

     

    * Try very different gauges. Thin is not always worse!

    4. Blend is a linear positive line from 0 to 100%.

     

    6. If I modify the knob mapping for all the Toneprints I'm going to use, and make the knob mapping identical for each Toneprint, will that affect the sound of the Toneprint? 

    4) Do you really need the blend when you are already in deep with all parametres? I don't see any benefit with dry signal, when the levels, and processing can be tweaked with such finesse. For me ON is 100 % ON, and therefore I have used the blend knob for other parametres. After all, by compressions nature, signal level has usually areas, where compression is not present at all.

     

    6) I have not seen this happening. Sounds strange if everything is set only to different places. Have you really checked every function and value there is?

    ...whether passive pickups would allow greater flexibility and the ability to try various different external preamps and hearing major differences, as opposed to active pickups which already use a preamp which has a certain profile.

    Again, @Boodang wrote some very good notes.

     

    I want to add that as long as you use any passive, hi-Z components in between the pickups and the preamp, the response is sacrificed. Any pot, be it blend, vol, or tone, will degrade the original sound.

     

    You want pure sound from the pickup, connect it directly to the preamp. You have two pickups, you should use some non-loading circuitry (Noll Mixpot or similar) between the two, or use two preamps, one for each pickup.

    ...it’s alnico2 magnets on the bridge for more mids, and alnico5 on the neck for more bass...

     

    Magnet type does not dictate the response of a pickup. The type may tell you the highest possible field it can produce around it, but that depends on the production process. Therefore a neodymium can be weaker than a ferrite.

    ...active pups have an op amp so they are buffered. This means that you could blend two active pups in parallel but you can't put them in series. So you can't install a series/parallel switch on a bass with active pups.

     

    There are pickups like EMG TW and TWX:

  5. pickup - vol - tone stack - output

     

    pickups - blend (or vol) - vol - tone stack - output

     

    Practically any component can be battery powered (low impedance, "active"). Some system are even PSU operated (like Alembic Series II).

     

    Coil-magnet pickups are "passive" (high impedance, hi-Z) components. As @Boodang so well put earlier, the basic idea to modify a "passive" pickup to an "active" one, is to add a buffer to it (EMG and few others). Then the lower output can also be compensated with that buffer. Yes, there are active units like infra red sensors, but they are rare. I have used an acceleration sensor: response starts from DC... amplifier cries... the system has now some HP filtering.

     

    NOTE: The output of a pickup can be adjusted by the amount of windings, or the buffer settings. Hi-Z pickup output may be far more powerful than its lo-Z sibling's.

     

    The most common way to mix two pickups is to use two vol pots. Pots are of mediocre quality, but very cheap - and therefore so common. The complicated thing is that this way of mixing loads pickups: the sound is affected. Vol pots are tone pots, too.

     

    Some preamps are mixers (John East, Noll Mixpot). They can adjust the levels of the pickups without loading the pickups. This way the blend adjustment is independent from each pickup, which certainly is not the case with a simple potentiometer based system.

     

    Tone stack may be just a cap and a pot. Cheapo, but functional. If you see an ad of an "active bass", usually only the tone stack is battery powered. Did you notice that a £300 Sadowsky preamp has simple vol and blend pots in front of B&T?

     

    A battery powered tone stack may be a tone, a filter (LPF), a two or a three band eq, a tilt eq, a semi-parametric... or nearly anything. There has been lots of solutions, although B&T is probably the most common at the moment. It is cheap, modern opamps have ultra low power consumption, and many of us like its simplicity.

     

    One thing that you should find out yourself is the output impedance. It affects (this is something I have found out by testing lots of stuff, and interviewing people) the input of OD/dist/fuzz and some compressor pedals (I have different pedal boards for hi-Z and lo-Z basses). Maybe your pedals are less critical, some of mine aren't.

     

    I do not see any reason you couldn't use an external preamp with any bass you have. You can use any effect pedal, and you can use any preamp you want. Trust your ears. Do not rely on opinions, only your ears. Like OC-2 was made for g-word players. Then Pino found it.

  6. Just a sidestep: years ago I was playing a small tour in Switzerland. Salzhaus promised to rent all equipment our band needed. My set was an old 4x10, and that fab Mesa 400+! That is one powerful and well behaving amp. It is still pretty expensive, but the glow of the tubes and sound it produces... I am using a solid state Glockenklang Soul, because it weighs much less.
