Very strange. Assuming the same chemistry and a similar SoC it should be fine for 9 V also. Maybe one was dead or something.

Intuitively it should, in actual practice not so much.

It would have been a wise decision to measure the current the preamp uses. No big deal, open one connection of the 9 volts clip, get a multimeter in current mode (very important!) and put it in between. For the current range start with 2 amps and switch down to 200 MilliAmps if it is below that.
For practical reasons use a fresh 9 volts battery and connect it and measure the voltage (!) every few hours at the clip. If it goes below 8 volts the battery is almost dead, but check with the amp if the volume is still useable and undistorted every time you measure the voltage.

Strung up the bass, brought it carefully into tune, and so far so good. Not even a creak as everything settled into place.
I guess I can exhale now.

I want to take a minute to thank all of you who have enjoyed my build thread. I have really enjoyed building this bass, and am realizing that with the exception of final finish work, I am very nearly done with the all of the building. Really the only piece left is installing the battery and jack. I'm sure final setup will come as I learn to play it.
I also want to wish all of you the merriest of Christmases to those of you who do, and a very happy holidays to all.

My wonderful wife got me a case for the bass. (It was on my Amazon wish list) I'll have to add some foam to more securely hold the instrument, and add some cut outs for bows, strings, and other accessories.
I also bought an EUB stand for it. (The Ingles adjustable cello and bass stand.) Based on the pictures and reviews, I believe that it will adequately hold the bass.

Thank you for sharing your journey with us! It's been instructive and fun.
Oh, I will post more pictures of the finishing process as well as the obligatory NBD post.
Ok, I have been racking my brain trying to figure out what kind of foam to use for the case. I can see 2 paths to take.
Option 1, buy a block of upholstery foam that fills the case, and then cut out like 90% of it.
Option 2, buy thinner foam and some kind of rigid material to build a foam covered frame around the bass and any openings I want.
In both cases, I would add a fabric covering for the foam.
Option 2 seems like the way to go, using say 1 inch foam over corrugated plastic material.

Finished up the electronics today. Installing the jack was a trick, as the wood was thicker than expected. I recessed the washer and it set in just fine. Once I got all the stuff installed and was able to close up the back and plug it in, all of the feedback issues went away.
Using the EQ controls, rolling off the treble eliminated the slight noise from the preamps and finger sqeaks. Adding some bass and it really sounds like an upright.
I should be able to get a recording together shortly.

Got the battery pack sorted. My earlier attempts with velcro were a failure. So I made a small baggie for it out of leather. Also you can kinda see how the electronics package fit inside.
I like how clean the back is...
Also received the stand, and it works! (Pictured with the longest foot for the bass which puts it at standing height)

That bow cutaway makes this the coolest design for an EUB I've personally ever seen.
Gorgeous!
... Cheers!

Use this stuff. I just bought a sheet of this to replace the disintegrating foam in a case for a Chapman Stick. It's much stiffer than upholstery foam, so it provides some structural support. It's also really easy to cut with a utility knife blade. Foam rubber requires special tools to cut it properly. Though an electric carving knife works, but will not give you a super-clean cut.
That's a really cool bass! Solving that jigsaw puzzle of piecing was seriously ambitious so congratulations for bringing it to reality.
Really cool reading ...I just found this after building my EUB
Could have saved me some time

That's interesting. Would love to see some details on that. Scale length, type of strings used, pickup choice, etc. etc.
I like the 2x4 construction! A friend of mine built a beautiful Telecaster out of knotty 2x4s, and it sounds as great as it looks!
It is laminated poplar
41 inch scale length
Fretboard has a 10 inch radius
Running a 5 string tobais jazz pick up
Straight out
The strings are from a place on
The internet that tunes up student instruments and resells the strings
I am still in the refining stage
But it plays great
Chop!!
