How useful is the Kubiki Drop D extension?


I came across this thread yesterday, and it's very similar to what I'm thinking of doing.
Also, I'm emailing Michihiro Matsuda regarding the construction process (became friends with him years ago, and actually saw him working on that weird Drop D guitar....thought it was another weird project he was working on at the time.)

It’s a great feature and brilliantly done. You can quickly change the E to a D and the scale patterns remain the same.
I don’t use the traditional Drop D tuner since it changes the scale patterns.
I wish it was available on other instruments in some form.
At the time, I wished it was available for lefties (AFAIK it never was). I certainly would have got one. An obvious self-seller. I'm surprised they didn't become more widespread; perhaps players found the tone less satisfying than what they'd played before? Or perhaps 5-strings became more common.

BTW/FWIW: it's Kubicki

Sorry for my mistake then. I don't know why I thought Kubickis used double ball-end strings. I was probably thinking of other headless basses. I stand corrected.

So with additional string options, Kubicki's creative design is less of an obstacle in that department then. The idea of getting the drop-D notes without breaking standard tuning or using a 5-string (closed D doesn't ring out like an open D) is a cool one. But what people say about Hipshot Xtenders being more retro-fittable and how some songs are more comfortable to finger on a traditional bass tuned DADG is valid too.
 
and how some songs are more comfortable to finger on a traditional bass tuned DADG is valid too.
Everyone will have their own opinion on this, but my experience in learning a bunch of drop D songs with the hipshot, then moving to the Kubicki, is that the Kubicki fingering is almost always easier or feels more natural. YMMV

Having also done it both ways, the Kubicki way is way more comfortable to play than drop D. I’d love a 30” ex factor below 7 pounds if I could get one. With different pickups and electronics. I never fully bonded with how mine sounded, but I loved the bridge and the d tuner. Allowed for more string options than anyone else’s design as well.
 
Hey JIO,

Just saying your build is super inspiring!
I hope mine is halfway as well conceived as yours.
Thanks for pioneering the way.
Thanks - my goal was to make it a one-step activation. (not lift & shift like Phil's) With the development of increasingly smaller active circuitry, the ultimate goal would be an accessible button pressed that would automatically trigger the capo on & off. Keeping it minimal/small is key as it could actually be done now with current technology. Think (battery powered) automatic shifting on road-bicycles which has become more common and reliable.

That's exactly what I'm hoping to build!

My wife doesn't get it, but I want something with consistent string tension...under 7 lb, and easy to play. I'm aiming for 4-5 lb
The Drop D is something that I can picture using when I'm able to evolve from total noob (learning to finger the bass) to mediocre (able to play basic bass).

ON a side note, would you recommend a standard length truss rod for this build?
Or something like 18" or 19"

Currently, I have 2 of the 22" wheel version.

I'll probably be copying bits of Jio's build, but with a P bass pickup (maybe also a J)...and using the Mezzaluna bass profile.

Duuuuuude! I'm nowhere as smart as you. Will probably need your help to dumb stuff done
