Hey there everybody! I'm just getting into this. About to finish my first acoustic three string CBG this week. (Then on to number two of course!)

I have a long term goal however, of constructing a full scale electric double base once my chops are up to the task. (That is double bass, as in "classical upright", not "double neck", though that would be AWESOME!)

Has anybody tried this or something similar? Can anybody link me to a resource for the measurements, materials? Got any advice?

Just throwing this out there to see what comes back.

Thanks!

-Micah

I'm currently working on one myself. I used a 41" scale, with a 33" fingerboard (1.5" wide at the nut and 3.5" wide at the base and a 4" radius). Here's a link of what I've done so far. http://herringmeisterlist.blogspot.com/
I think the long scale length is the deal maker. Everything else is a matter of taste.

Awesome! Thank you man!
I saw a really cool suitcase bass kit online a while back. Here is a link to some testimonials about it, but I can't find the actual order page for it.
you might also look into the bogdon box bass.

Here is a video review of the the build process and a demo of it from bass player magazine.
For rough plans on a simple washtub double bass you should see Dennis Havlena http://www.dennishavlena.com/db.htm
Cardboard may produce a better sound, but it can't take much punishment.

Michael,

I dig the detachable neck for transport on the suitcase base. Now I'll be staying up at night until I can figure out a good way to incorporate that feature into a washtub bass. I was thinking I could use a large locking latch like those on a toolbox on the tailpiece. That way you can detune, unlatch, and then the strings would be free so the neck can be removed entirely. Teardown in less than one minute and re-assemble and tune in less than two -- ???

Definite inspiration from this piece.
It's not full scale, but after a few more smaller instruments I'd like to build one of these:

I think it would be a great alternative to an acoustic bass guitar.
Hey David, sweet build! I was thinking about your piezo problem. Have you considered going the Fishman route (make your own of course). I have it and I really like it. It has two piezos that are clamped ON TO the bridge between the E and A strings and between the D and G strings. This might give you more vibration but keep it from getting boomy.

Thanks for the kind words suggestion Ben. I played around with clamping the piezos between the strings. It helped some, but I’ve found these MEAS tabs respond better under pressure. I ended up cutting a slot on each side of the bridge about ¾” from the top and putting the piezo tabs in the slots – sort of like the feet on the sides of a traditional bass bridge. The pressure from the strings flex the slots and push down on the piezos just enough to get good, even volume. I’ll have to upload pictures this weekend. I’m still tweaking the nut and refining the bridge. I might end up spending as much time on the setup as I did building the thing.

Hey David, what did you use for your tuning machines?

I'm trying to source some and they are anything but cheap.

Thanks!
I used http://www.stewmac.com/shop/Tuners/Bass_tuners/Adjustable_Tension_B...

At $31.98 they are not cheap. I even had to drill a hole in the string slots for the E and A strings to accomodate the string's girth. Since I was trying to make this thing a nice as I could, I sprung for the tuners. In the future, I think I'll just use eye bolts.
