Homemade uke bass

While waiting for funding to buy a proper uke bass, I hacked one together using a 1/2 size first act guitar my kids never used. I'm amazed how good it sounds!

I took a badly lit video in my basement, played through a tc bh250 and tb110 and hartke kickback 12 cabs. I can't wait to use this on a gig!

Thanks, definitely better than it was as a guitar. An far as what I did, I'll issue the disclaimer that I am not very good working with my hands (building things that is...) but I have a creative mind. That being said, there are other people who have done this as well, and I got the idea from their youtube videos.

I pulled out the tuners, drilled the holes bigger (didn't have a big enough drill bit, so had to do some filing afterwards), used gb7 type tuners, 2 are upside down because I only had left side tuners, one broke while filing it for the e string to fit, but then I remembered I have a hipshot ultra lite that was removed from my birdsong to put on an extender key, so that's the e string tuner.

I bought a pickup on amazing for about $7, had to file the slot in the bridge to fit it, so that tailpiece is a little loose but I have a new on on order. I didn't put a preamp in this because it was just an experiment and I didn't want to risk cutting a large hole in it. It sounds good passive though, so I'm not worried, the tc seems to have a good input for the piezo pickup. I also bought the strings (Aquila thundergut) on amazon for $20.

I had to replac the guitar nut, and had a 1.5" precut nut, so it's too narrow, but I have one on order that should be long enough; in the meantime this will work.

Then I drilled holes in the body behind the bridge to give the strings a place to anchor. Getting the strings in and on was tricky, I had to fish it through the top and then maneuver it so I could reach it through the sound hole, then I could tie the knots and put the washer on. I would imagine the bass uke tuners would make this a little easier to restring.

Anyway, the guitar has been in our house for a few years and my kids never played it, so not including that, the total cost was less that $40. I'm surprised by how good it sounds honestly, so I'm going to guess one that is actually a bass uke is going to sound and play that much better. If I had actual woodworking skills and tools this probably would have taken about an hour. It took me basically the whole day and I'm sore right now, but it was worth it.

I going to bed, but I'll take a few photos with better lighting in the next couple of days and post them here.

And yes @pcake, the rondo one is what I will eventually get I think, the kala is out of my price range for now. I'm looking at the solid body one, which is $149. But we'll see, maybe I'll wind up digging the acoustic more. I should be able to use either one at gigs, and will definitely be recording with it.
 
you may be selling yourself short. your uke bass sounded well intonated and i'm sure that didn't happen by accident. can't wait to see the pics.

i have a kala rumble, and there's something to say about being able to hear it unplugged, but the solid bodies are tempting.
 
Photos as promised. New nut and bridge saddle, done as only I could screw them up... But they work. I have a new piezo pickup on the way that is flexible, it should fit in the bridge better and deal with the uneven bridge cavity for a more balanced sound. Now I sold a few things so I'm going to be ordering something from rondo's site very soon.

I used the tuners I had available, and broke one when filing, hence the mismatched tuners and reversed directions. At some point I'll get some bass uke tuners , maybe.

Great job! I have a ubass and they are a lot of fun. Mine is an older model without a preamp, and it sounded good, but when I run it through an fdeck high pass filter it turns into a monster! You may want to consider an fdeck or some type of preamp at some point. It makes a huge difference! Try not to use more than 3 wraps on the tuners. Folks have broke many a ubass hipshot tuners by having more than 3 wraps! The strings will keep stretching for awhile, so you will have to adjust accordingly.

Thanks! There are less than 3 wraps, it just doesn't look like it because the tuners are small and I didn't cut the ends. The Aquila strings are starting to "sausage" as well, I think I'm going to get the kala strings at some point. I'm pretty close to ordering a rondo uke bass, not sure about hollow or solidbody. I am just waiting for one more thing to sell (of 3 things) then I'm ordering.

Either way, this bass is fun!
 
Hi folks im new here. I discovered the u bass last year. Found it more fun than real bass and since im a poor musician with small hands im sticking with this instrument. But being a carpenter i decided to try to make some... First i transformed a 1/2 scale guitar... Good sound.. Then made a 3 string with a soprano uke... Not bad but too small.. Had to file the frets to make it fretless. Then i experimented with solid body and kala round wounds. Very good sound.. Ash body and neck out of one piece. Had to try a few different preamps before finding the "right" one. Here are a few pics. Any feedback would be interesting.

Thanx
 
I found the good trick to have the tuning precise... My bridge is not fixed to the body so i can find exactly where to place it for accurate tuning on every fret. Notice that the compensation is backwards with the polyurethane strings! I was also perplexed about this...
