I have been thinking about adding a six-string Bass VI to the 32" scale lineup for quite a while, and now that the fiver is in production, using that configuration as the platform makes a lot of sense.

I have also had inquiries about building an 8-string 32" scale bass.

It looks like the Kahler 2450-N6 will do the job on the six-string, single-course front.

I'm guessing the ABM 3208 will do the job on the 8-string, double-course front, but I can't find a dimensional drawing or specs for that model.

It almost seems like it's been discontinued on the ABM site, but is still in stock at Allparts so I'll give them a ring to see if they have a spec sheet.

Are there any others out there that I should look into?

I used the Schaller STM roller bridge on two EB0 to EB6 conversions, one with a stoptail and one with a bigsby.
Works like a charm, but you will need to match the rollers to the string diameter. Done quickly with the roller mounted
on a drill, and a ratttail file. May not be what you look for, but it's an option.

Schaller makes a great 8 saddle bridge. Good price on this one - https://reverb.com/item/5105120-schaller-471-8-8-string-bass-bridge

Nice!

It looks like the Schaller 471-8 is no longer being produced, but they are still available on the used market.

On the Schaller STM, I like the looks of that, but it's much too narrow for my application.

After thinking about this some more, having custom saddles fabricated for my 5-string bridge plate is definitely a possibility for the 6-string option.

With spacing at 2 7/8", traditional barrel saddles would be about 0.57" wide and I believe that's wide enough for them to be stable under bass strings.

The 8 string is another matter entirely...there's too much engineering involved to make a small batch feasible.

Forgot to mention that I've got the big Kahler bridge on my Peavey TL-Six. Swapped out the nasty worn gold for chrome.  :mrgreen:

Using your stock bridge plate for the 6 seems like a good idea. And yeah, making an 8 is more trouble than it's worth.

The current Hagstrom 8s have an interesting looking bridge. Not sure if they're proprietary, or maybe Gotoh or something?

Thanks, and agreed!

I'm guessing there is a source out there somewhere for the Hagstrom and Musicvox 12-string bridges.

On the five and six string versions of the neck, I'm tinkering with the 2+2 headstock shape in MS Paint to see what a 3+2 and 3+3 might look like.

I like it!

I've been secretly building my dream Lowe bass in my head, and a 3+2 Ridler-style headstock is part of it.  ;D

As a follow up and for posterity, a few potential sources for 8-string bridges are:

SUNG IL (used on LTD/Schecter)
ABM Allparts
ETS Bass & Guitar Hardware
Warwick
Alembic

None of those links are opening for me.

I just heard back from ETS and they offer both 8 and 12-string options.

I don't have any technical drawings, but the bridge seems to float in a manner similar to a jazz-box guitar.

Yes. Some good options there. The Warwick looks great.

So, an interesting update.

I have been thinking about the dearth of 8-string bridges on the market and what novel design options might be available to address the void.

I drew something up today that I think will work and sent it to a good friend who is a a patent attorney and also a bass player.

His initial impression is that the idea could qualify for a design patent.

Needless to say, I'm pretty excited about that.
