This is not an easy task if your customer hasn't been thinking of the details at all. I had similar possibility with a local luthier few years ago. He was good enough to interpret my thoughts to shapes and ideas. It took over two months, numerous WA messages and phone calls before he was able to start. Slow speed was very helpful. We had time to consider the ideas and changed quite a few details during the design phase. 36", light weight (under 7 lbs.), small body, birch, walnut, blackwood, oil, a hi-Z humbucker, a step attenuator and a coil switch. Square neck, plays like a dream.

The top one is for lo-Z (active) basses and the other for hi-Z. The Tick dictates the size. Plates are simple perforated aluminium.

Reflex, if you can find one. The production has ended. https://www.sourceaudio.net/reflex-expression-controller.html

Dropping the load is fatal to the output transformer and it can melt. That is more expensive and complicated to replace than valves. Wish you luck with the unit.

Modulus Graphite user manual: "Chechen fingerboards may benefit from an application of gunstock oil or similar light oil, generally during winter months when humidity is low. Test the Chechen fingerboard by dropping one drop of water onto the board to see how long it takes to soak in. If the drop of water takes less than 10-20 seconds to disappear, the board needs a light coat of oil. Use a clean cloth slightly moistened with the oil. Gently and evenly rub it into the wood fingerboard. Allow the oil to soak in for a minute, and then wipe off the excess."

Are all valves in place? Anything loose? Cables checked? I do not rely on any component, if this kind of issue was found. Put the first cab back. Turn the amp on. Take a pencil or similar wooden stick and knock all valves through. Any funny noise or change in the behaviour, and you have probably found the place of the fault.

I know, I just had to.

Exactly, gambas can have multiple strings, frets, bows... and gambas descend from the vihuela, as you noted.

The cables tend to be pretty thin but molded ones have been reliable if they do not move too much. A bit too long cable can be tied to the board.

Ahem, I think this is one interesting PCB... any chance to get a board or at least the data of it, please?

Remember Antonio made 11 viola da gambas, which is the real predecessor of the double bass and later...

Excellent! If the link does not work, this will. My browser tried to reach it as https with no success, but http worked. http://www.solodoublebassrecordings.blogspot.com/

Sir, you are quite right, but many people think that the change would be in the same decade as watts (300 W to 600 W). I do not see that it is reasonable to emphasize power, but dBs. This monitor speaker can be our reference to few calculations (not for you Sir F., you know this stuff): https://products.electrovoice.com/emea/en/elx200-12/ sensitivity 93 dB / 1 W / 1 m continuous power handling 300 watts / 8 ohm (1200 W peak) max theoretical SPL: 128 dB / 1 m The amp mentioned can produce up to 300 watts per speaker. 1 watt produces 93 dB from this speaker (see sensitivity), 2 watts 96 dB, 4 W 99 dB, 8 W 102 dB, 16 W 105 dB, 32 W 108 dB, 64 W 111 dB, 128 W 114 dB, 250 W 117 dB, 500 W 120 dB (threshold of pain), 1 kW 123 dB, 2 kW 126 dB. From the previous list we can take the numbers 250 W (the amp was 300 W) and 117 dB. With two speakers we can get +6 dB and this will be equal a total of 123 dB with two speakers. A good thing is to understand that if the speaker was capable of eating lots of watts to produce decibels, the amp should be able to push 1 kW to reach the mentioned decibel level. Here we see that some extra watts do not automatically equal much more loudness.

Would a three band parametric help you? There are few, but they seem to be somewhat rare. WMD, Empress...

Power has a bit to do with the volume. But only a bit. If your amp has 10 watts, the next step is to buy a 100 watt amp. Next similar change requires a 1 000 watt amp. The difference between 100 W and 300 W is not so big. dB is about the volume. Sensitivity can help you to calculate how much volume you can get from the cab and amp. Impedance is like a stick. When it gets smaller (32 - 16 - 8 - 4 - 2 - 1), the stick gets thinner (from baseball bat to a needle) and it is harder to push with your finger. Amp gets warmer the smaller the impedance. This is because the amperes (A) start to rise which warm the amplifier section. If you double the number of cabs, you get smaller impedance, higher amperes (if your amp can push more watts to a harder load), and slightly more volume. This is around 2 - 6 dB, which can be heard, but it definitely is not so big change. It is common, that the placement of the cab can help player to hear details of the instrument far better than simple increment of power.

You just took over £40 k from their income. Bad boy!

Lady Dawn even called me in person to inform the neck was ready to ship. I could have listened her voice all day!

https://www.basschat.co.uk/topic/444788-experimental-prototype-bass-i-hope/page/9/#comments There's a cost analysis, if you want to calculate the profit. I used the minimum wages £8.91, but do you think his work is worth some more, do you? My guess is that the personnel at WAL can live with their work, but I doubt that's a gold mine. Let's say they (I assume there are only 2 persons, and I have excluded all outsourced work) build 4 instruments per month, around 40 per year (holidays etc.). 40 x £7 000 = £280 000. Subtract parts that may be something like £700 / instrument, round a little in case something breaks = £30 000. We have now £250 000 left. The very low rental of the workshop is £1 250 / month = £15 000. £235 000 left. Because the workers need to pay pension costs (£1 200 / month / person), insurance (£3 000), update tools (£ 1 000) etc. these yearly costs could be in the ballpark of £35 000. I need to point out that this is very rough guestimation and the costs are probably substantially higher. £200 000 left. Divide this to two, and we get £100 000 per person, which is £8 300 / month and after taxes maybe £5 500 / month. Gold diggers? I might call them hard working men.

Some think one screw is enough: https://reverb.com/item/35579498-journey-instruments-ob660-collapsible-acoustic-bass-carbon-fiber-travel-bass

Felix was German. La chanson de Roland is French. Do these two together make Japan? Or just hot air? Who am I? Is there any beer? [screams and runs away...]

http://web.daddario.com/StringTensionPro/ Depending on the tension values / gauges, there can be very little difference between the B and the G strings. This equals that if you change one to another, there's practically no need to adjust the truss rod.

No I don't. But that seems like 20 lbs.
