  1. 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.

  2. 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.

    Physics. Hoffman's Iron Law states that the three parameters that affect speaker performance in a cabinet...

    Exactly. Plasma elements were an interesting trial, but efficiency... The only way the performance could be enhanced, would be very different technology. Planar elements are big and lightweight - and lack low end. There doesn't seem to be solutions available that could replace this age old coil-magnet thing. Neodymium magnets were one very positive enhancement, but the efficiency is still in the ballpark of single numbers, like 1 - 2 %.

  4. I would love to write a hypothetical story about a man living in the '50s, and his name could be Feo, so back in the days...

    ...but today there are balance pots readily available contrary to the ancient times. Just buy a Bourns 250k MN, or 500k MN.

     

    If you put one point (jack ground, or the closest pot cover) as the centre point, you can connect every ground wire to that one particular (star) ground. In the schema the wires are chained from one point to another. Star is a better way to handle certain issues: do some search, if needed.

     

    When you rewire the set, pickups go first to the blend:

    pickups - blend - vol - tone - output

    This is the signal path! You certainly want to put vol closest to your hands to the bass' top: wires have to be long enough.

    BUT, something with a max of 9v power supply. The Bongo’s 18v is too hot for my needs.

    2 x 9 V may be chosen for simpler electronics. Two sided power is very easy to execute. If you use only a single battery, you need to divide the 9 V to 2 x 4.5 V.

     

    The level of the output signal is dependent on the choices electronics designer has made. It can be lower than those hi-Z counterparts, i.e. those without batteries.

     

    By the way, Status has produced a preamp with 4 x 9 V batteries = 36 volt circuitry. I think it was made for Jonas Hellborg.

  6. I'd be interested in the manufacturing country. If it is the big C, no. If Japan or even S. Korea, then maybe.

     

    European luthiers are so numerous that you can get a custom neck from the east side for a very attractive price, even from local guys. Why should I choose Asian?

  7. If you want to try something we have already done:

    - boiling

    - washing machine

    - ultrasonic

    - acids

    - solvents

    - nearly anything imaginable

     

    After some trials to save anything (except the time wasted), the best option is to go to your local store and by new sets.
