2 String Paddle Bass





Introduction: 2 String Paddle Bass

This bass is made from a wooden boat paddle, a piezo buzzer, weed eater strings and a few other odds and ends. For what it is and how little it costs (20-25 dollars with all new parts), the quality of sound is unbelievable. If you're thinking about taking up bass or already do and just want to have something different, this definitely would be worth making.

Here is a rough (aka bad) video to demonstrate how it sounds with no effects:


Also, here are some references and inspiration:





Step 1: Materials

42" paddle
machine heads
metal casing from hanging work light
1" piezo buzzer
1/4" jack
thick felt with adhesive back
two different gauge weed eater strings (I used .65 and .80 that I tuned to E and B)
various nails and screws
a pencil split down the middle

As far as the paddle goes, I used a SeaSense from Wal-Mart, but I'd suggest to try to get one from a sporting or camping store mainly because mine seems flimsier than others of the same brand but from another store.

Also, the machine heads can be either for a bass or guitar; a guitar machine head can hold a piece of .80 weed eater string with no problem.

Step 2: Drilling and Stringing

First things first, decide the scale length you want your bass to be (it probably shouldn't be under 30"). Next, measure that length from where the shaft starts tapering near the handle, because that is where the nut will be. An inch and a half behind the desired length, drill two small holes less than a half inch apart in the middle of the flat section of the paddle.

My scale is 32" but in the beginning I wanted 36". That didn't work for me because there were dead spots that won't make sounds for some reason. So I have holes drilled 5 inches behind were my piezo is, but it still works fine.

Now it's time to put in the machine heads. Find an appropriate size drill bit and start in the flat part of the handle. This isn't an exact science, just make sure the holes allow you to turn the key of the tuner and that both machine heads are pretty symmetrical looking. Once that's done, just screw them in.

Tie your strings into tight knots and send the untied end through the holes, over the split pencil/future nut and keep them loosely in place by only turning the machines once or twice.

Step 3: Finishing the Headstock

Trim down the pencil so it doesn't hang off the sides. If the strings are too close to the sides for you liking (which they probably will be) then put a screw into the handle on the outer sides of them. You may want to do this anyway because it seemed to work better for me than trying to cut slits into the pencil.

Step 4: Making the Piezo Pickup

you can either buy a piezo buzzer from somewhere like Radio Shack or take one from an small electric appliance, like an alarm clock. I bought a piezo and removed the black plastic cover so I could get to the good stuff.

Next, get that thick felt stuff (like the kind you put on the bottom of furniture) and cut two pieces to around 2" wide and 1" tall. Sandwich the piezo in the middle of the felt (metal side up) and place the front of the pickup at the end of the scale length and put two small nails on both sides to hold in place.

To check if it's working, just twist the wires around the connections on the jack (polarity doesn't matter) and if it's working and making sound, disconnect the piezo so you can put the cover on that holds the jack.

i have to give credit to the guy who made this:


Without this felt idea, this would be a screeching/popping mess. Trust me, I tried.

Step 5: Body Work

The work light casting will cover the pick up and provide a simple place to put the jack. You can buy the metal part by itself for about 3 or 4 dollars. Use the pre-made hole closest to the pick up to drill large enough to place the jack. Flatten out the extended parts (check the picture) so the casting can cover the strings without touching them. Now, just use some random screws to hold it down, two in the flattened part and one on the top toward the back in another pre-made hole.

For a strap button on the body, I used a roofing nail (be careful- don't split the wood if you do this) I had a hundred of laying around. For the one on the neck, I put a big headed screw where it felt right for the bass to hang and not be too in the way.

Step 6: Finished and Other Ideas

Now all you need to do is tune it up and plug it in!

But if you'd like to draw in some frets or even put some in (ambitious!) here's a good fret calculator.


If you can't stop at just frets, make a fret board. My bass still has a spot under the E string that won't make a decent sound (I think there may be a knot under it or something). A strip of 3/4" wide wood or metal glued on or flat screwed down seems good in theory, but I haven't tried anything yet.

Heck, why do you even need two strings? Just put one on!

If you're a fan of upright basses, I've been thinking that someone could rig a fix topped guitar stand to hold one of these- that would be interesting.

Also, you could drill the string holes at the top of the handle and the machine heads at the bottom for more of a headless look and better balance (although the regular way has a good balance anyway).

Well, have fun and good luck with your new bass!

    if you had more than 2 strings and only one pickup the outside strings might be quieter than the middle ones.

    I never saw a bass like this before!
    You can make music out of anything!
    You can get individual machine heads and bass strings at Janikas Music Shop


    thanks for the head's up!

    Dude where did u get those machine heads from??

    from guitar center. i didnt put on the little metal cover that goes over the gears.

    they were 20 when i got them, but i wont be surprised if they are more now.

    This looks awesome, i want one!

    great project! just made one myself (had all parts at home) - it sounds incredible for how it's made. Only thing not so good is machine heads, I used those from an old classical guitar, but they're too small for bass cords..

    You say you got your machine heads from guitarcenter, but the lowest machine head I can find there is for 59€, and you said total cost is 20-25$... could you give a link to the machine heads?
