Picture of Knex bass guitar (Harp)
This is a tunable bass guitar - that I am going to add to Knex band.

You can actually get a tune out of it and it sounds much like a bass (However i am not a bass player so i wouldn't know well).

I managed to get 'Smoke on the water' out of it and it sounded pretty realistic, however all the videos i took on it do not sound like it does in real life - you can't really tell much difference between this and a drum kit in them.

It has four strings, and although being a bass it looks nothing like a real one - so maybe i should call it a harp.

Build

1) frames
2) tuning edge
3) base edge

Oh, and get a box the size of a PS3 box.

Step 2: The Base Plate

This would be the fretboard on a normal guitar.

1) make
2) make the extra bits
3) add the extra bits on to no.1 - the holes go on the whites. Attach the grey cons to the end whites to allow flexibility.

Step 3: Attaching Them Together

1) Well, that was easy.
2) Attach the base holder thing to the leftern most part.
3) Attach the tuning holder thing to the rightern most part.
4) Get some of these for the next step (Yep, they need to be broken)

Step 4: Strings

1) Do this kind of knot (it is quite simple) and do it to the other end to.

2) Attach to the base, holder.

3) Attach to the other end (the pic is a close up of all four when tuned.

Awesome. One of the very few k'nex I'bles that I actually like. Do you play the bass? I do.

yay! i did the impossible lol. nah, i dont play bass, although i would like to... im playin electric at the mo. d'you have facebook?
Camisado barrax5 years ago
Haha, yeah, you did the impossible alright. That's cool. If you decided to play bass, I suggest you start of with an iBanez. Those are cheap and the quality is just perfect. I do, actually. My Facebook is "Petrov Iliaj Cravic".
i buyed a YAMAHA bass guitar, WITH amplifier, tuning device-thingy (dunno how to say that xD lolz), bag 4 the guitar, and some other stuff, don't get a heartattack: 150 EURO'S!!!!!!!!!!!!!!!!!!!!! normally 400 or more euro's!!!!!! very very very cheap and really good to start with ^^
Haha nice. And I believe that "tuning device-thingy" is called an amplifier.
no that´s not it... it´s a tuning device to tune your bass guitar to the right tone.
Oh. So not an amplifier? Hmm. Given your vague description, I don't think I can help out much, sorry.
haha yeah that doesn't matter, i only don't know how to say what it is in 1 word xD
I cant believe NO ONE knows what it is called. It''s called a tuner, unless it's a cylinder. Then it's a pitchpipe.....we need better music classes
Excuse me that I'm not from an English speaking country ;)
I LOVE playin bass. Especially Pumped Up Kicks and Sunshine of Your Love.

why is it in a box?
barrax (author)  knexsniper15 years ago
so you can actually hear it. take an acoustic guitar for example. what is the wood? a shaped box with a circular hole at the top.
oh, i thought it was because you put it there, does t work? i mean, can you play music with it?
barrax (author)  knexsniper15 years ago
just about. but that depends on the bands, and the way you tune/play it.

Even if you're not happy with the quality, you need to post a recording or video of the sound it makes.
