    That's what it means, but for the most part it's not the case... PA boxes tend to use better high frequency components, which allows a lower crossover frequency. That doesn't make response any wider.

    True, and a good point. Quite many combos have only the woofer, so my point was a simplification, as was my short text in general.

  2. Sessionette 100 (15" combo)

    GK 200MB (12" 100 W second gen combo)

    Peavey Databass (15" 450 W combo)

    Glockenklang Soul (2x10" 450 W combo)

    Soul head from the combo and alusonic 2x12" cab

     

    GK had excellent sound. Soul combo has top sound too, but weighs a metric ton. I separated the head from the combo to a rack case and bought the alusonic. Easier to carry.

  3. A PA cab, a powered speaker without the preamp of a bass amp. It still may have a simple eq, or some adjustments, like gain.

     

    Full range means wider response than of a bass combo.

     

    Flat response should mean flat, but I say that it is still far from hifi.

    You'll notice that your 4Ω cab is MUCH louder than the 8Ω, as it allows the full 250W to be delivered to the cab, but it's possible.

    Really... we are talking about few decibels... if the 4 ohm version is much more sensitive, I'd buy that. Otherwise not.

     

    Sometimes an 8 ohm impedance speaker may be louder than a 4 ohm counterpart.

    It's tough trying to find a suitable on-board pre-amp for three pickups. Everything seems to be geared towards dual pickup, which is understandable really.

    What? There are only very, very few preamps for two pickups only.

     

    Most of the preamps are after simple blend and vol, or vol and vol. In a three pickup version you could have three volumes. If you want to put an active tone stack after every pickup, you just need more space.

     

    It seems that you have not checked my simple drawings of the bass signal path, once more:

     

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

     

    In your case you just exclude the blend and put in there three volumes. The tone stack is up to you: a battery operated preamp, or a capacitor based, simple passive tone x 1 - 3.

    An other thing about using a Series box is that you will not get all the power out of the amp that it's capable of.

     

    When buying an amplifier to use with your existing speaker cabinets it's wise to consider their impedances and verify that the amplifier is capable of driving them safely. 

    The first sentence should point out that the difference in dBs is minimal. So many watts, so little decibels.

     

    The second comment is feasible. Usually if your main cab is 8 ohms or more, another cab is a potential possibility for more loudness.

  7. I have written a few times about signal path. Please find it if in need.

     

    The system that consists of many switches and maybe even ser/par option might be usable, if you make it happen with a rotary switch. Otherwise there will be many options, where the sound is off, or switches are excluded from the line. That would mean that you'd need to learn to walk in the switch jungle.

     

    I would start from feasible sounds: what is functional, what is not. After the options are charted, someone familiar with electronics finds the parts you need and puts them together. Otherwise there will be non-usable situations, and you may cut the sound in a band context just by accident.

  8. The basic idea is simple: you have two necks with similar screw holes and you make a change. That's it.

     

    Along came tolerances.

     

    It may be so that you need to shim the other neck to get the angle right. This is simple. Few plastic sheets, sized 1 cm x 4 cm x 1-2 mm or so.

     

    Neck pocket may be loose or tight. Your choice: the pocket or the neck heel needs some sanding.

     

    If the screw holes do not fit, consider using DIN 7965 slotted inserts after filling the holes of the neck, and drilling new ones that fit. The slotted end goes in first: 

     

    Sure you have to change strings and check the fine tuning and string height, but that takes less than half an hour. You need a tuner and few tools.
