Interesting. The Reverb seller I got this from insisted I use these gauges and brand as seen in the pic. I can’t say I have much to draw on as far as comparison, but for the grade of bass this is I don’t think it could be more playable

.40/.18 .60/.28 .80/.40 .100/.50 .125/.60

What I posted is from a 2008 TalkBass NBD post. The specs would have been on Dean’s website back then, so I’d believe them more than a seller who isn’t familiar with Dean basses 13 years later.

A cheap digital caliper can ease your concerns. They’re around $10 on ebay.

The strings recommended are all slightly thinner so I’m guessing they’re a lighter gauge. They might be too loose in the nut?

However, they may also be better for the neck with less stress on the neck?

I still have the same strings on mine that it came with so I’ll need to nail this down too.

@Beersurgeon might know as he owns one as well.

Also, since @Ric5 is all over 5 strings and used to own the same bass he might know better than I as well

Remember these are octave courses. The double strings are an octave apart.

neat score and a fine-looking piece! hope you're able to rock-the-house with it --- congratulations on your new instrument!

Someone here might be able to answer this better than I.

I don't want to say he outright made them up, but the high-octave side of the gauges given by the poster from 2008 would be better suited for a 5-string bass tuned EADGC rather than BEADG.

The rule of thumb is having the octave strings's diameters at half those of the corresponding lower counterpart ensures similar tensions for any given pair.
I know *this* sounds made up, but it is confirmed by geometry and physics. Assuming identical or proportional, scaled-up construction (which ain't necessarily so, in the real world, but tends to be close enough), and half the diameter of a given length being one quarter the volume (per the volume-of-cylinder formula), it also = 1/4 the mass, which, scale being equal, gives the same tension but an octave higher, per this formula:
T = [UW x (2 x L x F)^2] / 386.4
where T:tension, L:length, F:frequency, 386.4:conversion factor for inches of length and pounds of weight, UW:"unit weight" or pounds of mass per linear inch.
If you go to the old D'Addario string tension chart, page 9 (10 of pdf), right-hand column, and check unit weights for strings XLB040 and XLB080 you'll see that the latter's is about 4 times the former's, and that they have very close tensions when tuned to A (42.5 lbs) and A' (42 lbs), which are, in Helmholtz pitch notation, the same as respectively A2 and A1 in Scientific Pitch Notation (in other words, one is open A string on guitar, the other on bass). This holds true for any pair of strings from the same product line whose gauges are one double the other.
[As in: when unit weight of the fatter string happens to be more than 4 times that of the thinner, its tension will be accordingly higher when they're tuned one octave apart. This just means one string is internally built to be denser than the other and tension values reflect that. However, you'll rarely encounter tension differences larger than a couple pounds (unless one of the strings is plain, ergo fuller, and the other wound, ergo gappy).]

Now, there may be other considerations than just "equal tension within each pair". So, by all means, do experiment with gauges if they don't feel right.

Interesting.

A 15-string would be cool if it could be done without the neck being too wide. 5-string with 2 drones per string.

I believe Warrior has made or makes one.

We'll get to the 'right' answer soon, I'm sure of it, with all the knowledge here on Talk Bass how can we not?

Someone in these threads or websites might be able to help.
I'd think @Bruce Johnson could help?

I don't remember the exact gauges we used on the Marvin 10-strings, but I think it was a standard D'Addario 8-string set, plus matching 0.125/0.065 strings for the B pair. I believe that's what Jeff Pilson is using on his.

I don't remember the exact gauges we used on the Marvin 10-strings, but I think it was a standard GHS 8-string set, plus matching GHS 0.125/0.065 strings for the B pair. I believe that's what Jeff Pilson is using on his.

Thanks for providing this!

The 8 string GHS Boomer set is
40(20) 55(25) 70(35) 90(45) so add 125(65) singles

I supervised the build of a 15-string almost 20 years ago... it turned out great!

I just saw Keith and asked him. He remembers that they were D'Addarios. Also, our 10-strings are 35" scale.

There's a reason it's so cheap. Somebody modded it to reverse the string courses a la Rickenbacker.

Not irreversible. If I had seen that one first I would have grabbed it and reverted it back to stock

You and @Marc61
Looks like someone bought it
