Digital Guitar Of The Future Has No Strings

August 1, 2025 by 16 Comments

Electric guitars are great, but they’re just so 20th century. You’d think decades of musicians riffing on the instrument would mean there are no hacks left in the humble axe. You’d think so, but you’d be wrong. [Michael], for one, has taken it upon himself to reinvent the electric guitar for the digital era.

Gone are the strings, and the frets have vanished as well. The neck of this guitar is one long custom PCB, looking very sleek with black solder mask. Gold pads serve as touch sensors to give tone data over i2c (from unspecified touch sensing chips) to the Amtel Mega 32u4 at the heart of the build.

With no strings, strumming won’t work, so a laptop-style touchpad serves instead. That means every user interaction with this guitar is with capacitive touch sensors talking i2c. The X and Y coordinates of the touch, along with pressure are sent to the processor over the i2c bus, triggering an interrupt and offering quite a bit of opportunity for sound control.

Said sound control is, of course, done in MIDI. This lets the guitar control a whole variety of synths and/or software, and of course [Michael] is using more futuristic-sounding synths than a pack of guitar samples. That said, what exactly goes on with the MIDI controls is left frustratingly vague. Obviously fretting provides note selection, but does the touchpad just send a “note start” command, or are the X, Y and pressure data used in interesting ways? Is there multitouch support? The video doesn’t say.

How, exactly, the obviously-plastic body of the guitar was manufactured is also left unsaid. Is it a large resin print? SLS? It looks injection-molded, but that makes no sense for a one-off prototype. On the other hand, it looks like he’s selling these, so it may very well be an injection-molded production case we’re seeing being assembled here, and not a prototype at all.

For all the video leaves us wanting more information, we can’t help but admit the end product both looks and sounds very cool. (Skip to the 4:50 mark in the embedded video to hear it in action.) The only thing that would improve it would be a hurdy-gurdy mode. Thanks to [Michael] for the tip, and remember  we want to hear tips about all the weird and wonderful hacked-together instruments you make or find on the web.

Cyberbass Brings Bass Guitar To Modern Era

February 4, 2025 by 19 Comments

For better or worse, the fundamental design of guitars has remained familiar since they electrified around a century ago. A few strings, a fretboard, and a body of some sort will get you most of the way there for an acoustic guitar, with the addition of electromagnetic pickups and wiring for electric variants. However, technology has advanced rapidly in the last 100 years outside the musical world, so if you want to see what possibilities lie ahead for modernizing guitars take a look at the Cyberbass created by [Matteo].

The guitar starts its life as many guitars do: with a block of wood. One of the design goals was to be able to use simple tools to build the guitar, so the shape of the instrument was honed with a Japanese hacksaw and the locations for the pickups and other electronics were carved out with chisels.

The neck of the guitar was outsourced since they take some pretty specialized tools to build, so simply bolting it to the body takes care of that part of the build, but [Matteo] had a few false starts setting the bridge in the exact location it needed to be.

Luckily he was able to repair the body and move the bridge. With the core of the guitar ready, it was on to paint and then to its custom electronics. [Matteo] built in not only a set of pickups and other common electric guitar parts but also integrated a synth pedal into the body as well as including a chromatic tuner.

With everything assembled and a few finishing touches added including a custom-engraved metal signature plate, the Cyberbass is ready to go on tour. [Matteo] learned a lot about guitar building in general, as well as a few things about electronics relating to musical instruments (including how expensive tuners work just as well as cheap ones).

You Can Use An Old Tape Deck As A Distortion Pedal

September 21, 2023 by 16 Comments

Distorted guitars were a big part of the rock revolution last century; we try to forget about the roll. As a youth, [David Hilowitz] couldn’t afford a loud aggressive amp, a distortion pedal, or even a proper electric guitar. This experience ended up teaching him that you can use random old audio hardware as a distortion effect.

[David’s] guitar journey started when he found a classical guitar on a dumpster. He learned to play, but longed for the sound of a proper electric guitar. Family friends gifted him a solitary pickup, intending he build a guitar, but he simply duct-taped it to his steel-strung classical instead. The only thing he lacked was an amp. He made do with an old stereo system and a record pre-amp. With his his faux-electric guitar plugged into the microphone input, he was blessed with a rudimentary but pleasant distortion that filled his heart with joy.

[David] goes on to explain the concepts behind distorted guitar sounds, and how his home hi-fi was able to serve as a passable starter amp when he was young and couldn’t afford better. He then goes on the hunt for more old gear at a local Goodwill store, finding a neat old tape deck that similarly produced some nice warm distorted tones. In [David’s] experience, old hi-fi gear with microphone inputs can generally do a decent job in this role, with electric guitar pickups typically overloading the preamps which expect a lower-level signal. It’s different to what you’d get from a Big Muff or Boss DS-1, but it’s a neat sound nonetheless.

We’ve looked at distortion effects before, including rolling your own and putting it into production. Video after the break.

A Kid’s Toy Guitar Turned Into An Electric Ukulele

December 15, 2022 by 8 Comments

With the holiday season fast approaching, there’s a good chance that some well-meaning friend or relative might buy a toy musical instrument for your children, safe in the knowledge that they’ll never have to listen to the results! The sound from these cheap toy guitars is pretty terrible, partly because they’re just too small to tune to a pleasing guitar tuning, so [joekutz] decided to see if one could be turned into an electric ukulele instead.

The first modification on the list was to reduce the string count from six to four, by notching out new positions on the nut and drilling the corresponding fixings on the bridge. One advantage of these cheap instruments is that it’s less of a risk to take tools to the bodywork!

A Guitar From Scratch

July 13, 2022 by 15 Comments

You can pursue your dreams of rock superstardom with any guitar, be it from an expensive luthier, a pawn shop, or a mail order catalog. But to join the ranks of rock greats there’s one way to have a truly special instrument, which is to build it yourself. [Bensoncraft] may not be [Bryan May]’s dad or indeed [Eddie van Halen], but he has at least joined the exclusive ranks of home made guitar builders with his video “Guitar from scratch: hard mode“.

It’s a fairly long video and we’ve placed it below the break, but a compelling one as we learn just how many operations go into making an electric guitar. When he says hard mode he’s not joking, there are no pre-made parts save for the strings and he’s not following a set of plans. Everything including the tuners and pickups are made from scratch, but for a non-guitar-player it’s she sheer number of different pieces of wood that go into making the solid body and neck of the instrument that’s so interesting. Even if you’ll never make a guitar you should watch it.

We’ve never seen a guitar build quite like this one before, but we have brought you a 3D printed guitar body, and neck.

Young Maker Mixes Traditional Japanese Construction With Modern Art

January 25, 2022 by 4 Comments

We’re Makers. By definition, we make things. Some of us prefer to build from scraps, while others like to make their own IC’s in their garage. [Make With Miles] on the other hand prefers one of the oldest types of making around: woodworking. And in this build, he goes a step further by using a very old Japanese method of woodworking called Kumiko to build a Stratocaster style electric guitar. The results are absolutely stunning as you can see in the video below.

Inspired by a challenge put forth by [The Modern Maker Podcast] to build a woodworking project that ties into another hobby that isn’t related to woodworking, [Miles] knocked it out of the park by including several art forms in this one-off Strat.

The centerpiece of this guitar build is the Kumiko style of construction used within the body. Kumiko is a Japanese method of assembling wood without the use of fasteners. Developed around 600-700AD, Kumiko is as much a construction method as an art form. [Miles] went further by filling the Kumiko framework with blackened epoxy resin which was then sanded and polished. Decals bring the headstock into the motif, but the attention to details goes much, much further. Be sure to watch the video so you can get an appreciation for the high level of workmanship that this young man displays.

That’s right- [Miles] isn’t a maker with decades of experience. In fact in 2017, one of his YouTube videos was “12 yr Old Builds a Row Boat!!!” [Miles], our hats are off to you and we look forward to seeing your art progress, for you truly have commanded the attention of the maker community that you are so rightfully part of.

Just as [Miles]’ guitar hides some great hacks, so does this guitar with Hot Swappable pickups. Thanks to [Keith] for sending this on to the Tip Line!

Active Pickguard Makes For A Great Guitar Mod

December 13, 2021 by 6 Comments

Much discussion goes on in the guitar world about the best hardware to use. Whether its pickups, how they’re positioned, or even the specific breed of wood on the fretboard, it’s all up for debate. [Eli Hughes] put much of that to one side, however, with his innovative “Active Pickguard” project.

The project reimagines the electronics of an electric guitar from the ground up. Instead of typical electromagnetic pickups, six individual piezo pickups are built into the bridge – one for each individual string. The outputs of these pickups is conditioned and then read by the analog-to-digital converter of a Freescale Kinetis K40. The DSP-capable chip can then be used to apply all manner of effects. [Eli] demonstrates the guitar providing an uncanny imitation of an acoustic guitar, before demonstrating jazz and overdrive tones as well.

The Kinetis chip also features touch-sensitive inputs, which [Eli] put to good use. All the hardware is built into a pickguard-shaped PCB, complete with touch controls for things like volume, tone, and choosing different DSP patches.

Unlike a regular guitar, this one needs a power supply, which it gets via a CAT 6 cable, in place of the usual 1/4″ guitar cable. The CAT 6 also carries audio out to a converter box which allows the audio to be output to a regular guitar amplifier.

It’s a neat build, and one that shows just how modern technology can reimagine a simple 20th-century instrument. DSP really is magic, after all. Video after the break.
