Depends on the LED board. There are both, CC and CV systems, there. Constant current is very common in luminaires, but especially stripes are using constant voltage drivers. It is very nice that there are lots of DALI drivers, but also Casambi (wireless) drivers have become widely available (Osram, Tridonic, TCI...).

You mean a g-word, or Gerald Veasley's Jabanez? https://www.ibanez.com/na/products/detail/gvb36_1p_04.html

Dear Tractor, you just don't understand the finesses of GyroDec. You need to listen to the sound it doesn't produce. A friend of mine changed his CD, because the mechanics made so much noise. I have an old Technics SL-1210 that I got for free, because it was filled with liquor, something that contains hell of a lot of sugar. I managed to clean the frames and to my surprise the electronics were intact. Had to buy a new cover and a platter cover and a cartridge that was NOS Shure V15 type III. It has been running for two decades with no issues so far.

I could use a hammer, but I just like better tools. I am so bad player that I use instruments that help me to sound and feel better on stage. Fender is not the one. Nowadays expensive most likely means that I would love to have it but cannot afford it. On the other hand Fodera is not expensive because it doesn't interest me.

D6C is a complicated unit. Try to find someone who has manuals, tools and knows latest HW updates.

An addition.

I have used Tonar needles/styli. Work well, availability is decent, as is the price.

My MG Quantum 5 was expensive when I bought it new. I sold my piano, and used all my savings to buy it. In today's money it was nearly £5000. It was a good sounding bass, but since then I have played instruments that feel and suit me better. I sold it and bought an MG Genesis 5 here that may not look as fancy, but it feels so much better. That sure wasn't expensive because of its value to me, no matter the price! As there are very good used basses everywhere, I would seriously consider buying a bass that costs over £2000. I am not into vintage stuff at all, but a lightweight 5 string super long scale Overwater...

Jimmy Johnson is a super player. I sure cannot play the stuff he does but it is very interesting to follow his playing through your transcription. Once again, thank you @Bilbo.

The wood is looking so good, why bother? A double bass with dots/blocks would look... strange? Luminous side dots is another story.

@tauzero answered so well to the first question! Even 48 V high wattage (CV, constant voltage) stripes can withstand reverse voltage. 9 V to a 4.5 V stripe (very odd voltages, both of them) will degrade the lifetime a lot, if the system works well. Two similar systems can be connected in series to double the input voltage. It is feasible to connect the stripe to a driver before connecting the system to a line especially if the system is CC (constant current). Battery powered small systems should be able to manage hot swap, just like CV (constant voltage) systems.

No, there are no technical limitations. This has all the features you asked for: https://www.kdbasses.com/basses/rev-ii-5-string-multi-scale-headless/
