Ask Slashdot: Best Open Source License For Guitar? 102

Posted by samzenpus from the modular-guitar dept.
First time accepted submitter PraxisGuitars writes "I am working on developing an open source electric guitar. I wish to make the basic structural system completely open and free, with a standardized interface allowing different body shapes and modules to be bolted on. I am having trouble figuring out the best way to release the files. There seem to be at least half a dozen open source licenses out there; The Thingiverse has some precedent for open source 3d data, but version control seems like it might be difficult. I have looked into sourceforge and github, but don't know enough to know if that would be the best choice. Are there other precedents out there? Is there a better way?"

      I just checked OpenCores (the first of the hardware open source sites) and the preferred license is LGPL on there. I would say that if it's already in use for hardware specs and is working for that then it's a viable license to use.

    Why a license is necessary, or why it is an open-source guitar. The basic functionality of a guitar is well beyond reach of any patents or copyrights. And I read your website -- cheap guitars can be had for under $100 these days that are very good for a beginner. Basses are a little more but still, I can have a copy of Jaco Pastorius' bass for $275.

    I suppose there is some larger scheme here that I am missing. I know I couldn't play a guitar that looked like that. I would spend more time disentangling it from my clothes and cables than playing it!

      Well, some people, you know, like making stuff for themselves, rather than being just another consumer. It's infinitely more satisfying to make something than to buy it, even if it's more costly.

I believe that I have the most to gain by making the framework public domain

      • If you genuinely want other people to build them, you have to get rid of the non-commercial restriction mentioned on your site. You can't build a market from the handful of people with the interest, equipment and skills to do this.

    I find this absolutely fascinating. As someone who has spent some time in a guitar repair shop this makes a lot of sense. Or if it doesn't, it is at least not without some sense. I took a look and the Praxis Zero looks absolutely wicked. To have one of those on stage would draw endless praise and positive attention (speaking from the level of the local scene in a big town). A modular guitar is a great idea as I wouldn't have to "fret" so much over specs as I choose my next axe. Rather, I could just change the specs on my one machine. All makes and models of guitars sound different than all other makes and models - this I don't have to explain to you the particulars of. If I could transform my p-bass into a j-bass for one gig without having switch to a whole different kit that would be great. At the very least it would have a strong and worthwhile nitch. Unfortunately, I have no answers and only questions but I wanted to back you up that this isn't a dumb idea. Will there be a bass centric version?

      Modular guitars aren't new, and they've never been popular. Even modular on a smaller scale -- making pick-ups swappable without tools, for instance -- has never caught on with the public; Gibson tried it again just recently and the buying public gave a collective "who gives a fuck?"

    I'm curious: what part of the design of an electric guitar would not already be completely covered by prior art? Unless you do something really extraordinary with the electronics, which I wouldn't recommend because all that's best done downstream from your output jack, or have some really innovative tuning system (like the automated tuning done on new high end models of the Les Paul) there's not a lot that you're going to do that's going to be new and therefore license-able. The dimensions (or at least the ratios) are standard if you expect to stay in tune, and you can put your tuning pegs at one end of the strings or the other (ala Steinberg). I suppose you could create some innovative process for routing the body or planing the neck or come up with some fantastic new material with extraordinary acoustic properties. Maybe there's room for special design in truss rods or pickups. But I guess the question would be: why?

    How about this: Come up with a nicely designed electric guitar and release your design into the public domain. Then you don't have to worry about licenses at all. If it's a fantastic design, you'll get your recognition.

    I wonder: was the original Les Paul patented? I know humbucking pickups were, and certain tuning systems/bridges and designs for vibrato tailpieces.

I can already easily swap out the pickups- they're attached to the pickguard, and I can buy any number of pickguards preloaded with various pickups/electronics for a Strat. I can pull off the neck anytime I want and swap in a new one- it's only four screws, and there are a dozen companies out there that make Strat compatible necks.
