Gibson to Embed Guitars with Ethernet

caseyuw writes "Gibson is planning to roll out their Magic this year with the delivery of guitars using Cat 5 instead of analog cables to connect instruments and amplifiers. The debate over the quality of digital vs analog signal processing is not new, but using a 'Magic' Les Paul would force you entirely into the digital domain." We mentioned this last year, but the above article has much more information.

      1ms delay in a 100 ft cable? Not likely. Signals travel in a cable at about 1/2 the speed of light or about 6 inches per nanosecond. So a 100 ft cable will have a propagation delay of about 200 nanoseconds. That's a far cry from 1 ms (a.k.a. 1,000,000 nanoseconds).

      On the other hand, sound travels through air at about 1 foot per millisecond (roughly). So that 100 ft cable would put Jimi 100 ms away from the monitor speakers. At 4/4 time and 120 beats per minute that is almost a quarternote of latency. Clearly no riff-master would ever want to be off by that much.

      Likewise, you can think of latency as "adding distance between you and the speaker". For example, 1 ms of added latency is like adding another foot between you and the speaker. For most applications 5 ms isn't going to be noticeable, but the signal chain for a concert or studio can be long. And all those 5 ms delays really add up.

      Gibson Magic is really just a CobraNet wannabe (www.peakaudio.com).

      The guitar pickups, as far as I can tell, will still be analog. Thus, every guitar must have an A/D converter in the body. Having digital output will limit you to digital signal processors, unless you first convert back from D/A. You will find countless arguments supporting analog sound quality, I won't even attempt to address that issue. However, what quality do you think the onboard converter in the guitar will be?

Not to mention these prohibitively expensive gadets will only work with other prohibitively expensive gadgets that are compatible with the same format.

    Musicians care about *sound* and nothing else. If the best sound came out of a old transistor radio running FreeBSD modified with DDR ram and put in a hollowed out cardboard box, they would use that.

So. these guitars will be outfitted with cheap converters, destroying any chance for quality sound. Cheap converters add many artifacts to appear that are not musical. analog does of course add artifacts of their own, but these artifacts tend to be more musical and pleasing to our ear. ie:tube amps create a pleasing distortion when pushed sufficiently by the amp. But the digital artifacts are generally displeasing. physiologicaly. Also cheap converters have greater problems with things like jitter. Jitter is a phenomenom that occurs when the a/d converter is not perfectly in sync with the "system clock". this also causes artifacts to appear. I'd reccommend you let the studio do the d/a converting, as they probably invested some money into this very important component in digital recording.

    First, I wish them well, but the current Gibson management has a history of failed and ill-supported attempts to make new technology work in the music industry.

    Also, Gibson's shotgun-like litigious actions within the music industry within the past decade have caused the music industry to put little faith in its supporting a technology standard of *any* kind. The past actions of its current management will make music instrument manufacturers think twice (or more)before they adopt or even license Gibson technology.

    Some history:

    1) Gibson completely blew their opportunity as once-owners of the Oberheim name (which they inherited as part of a purchase). Poorly-defined and ill-marketed products killed the Oberheim brand; meddling by ownership didn't help...(recently the Oberheim name returned to its rightful owner, Tom Oberheim, who is nicely rebuilding the brand).

    2) Gibson bought Zeta Violin (a very innovative manufacturer of electronic violins and basses), and with it the services of the gifted engineer who who started Zeta. They had this engineer cobble together a MIDI substitute called ZIPPY. This at a time when MIDI was just getting a head of steam up. Gibson's ownership wanted to replace MIDI and collect license fees. Forget about helping to nurse a just-getting-off-the-ground standard, or MIDI). Talk about bad timing. ZIPPY died, and the engineer had a hand in regaining Zeta (a fine company these days).

    3) Next was Gibson's infamous purchase of Opcode Systems, a few years back. Opcode was a primary manufacturer of music software and hardware at the time - one of the best. They created the OMS standard, which the Mac music community was widely dependent on. They promised Opcode's then-owner an opportunity to start a little R&D Group and come up with a few new things. The whole thing died in an acrimonious lawsuit, and in the offing, Gibson destroyed Opcode, and OMS. What a waste.

    4) Unrelated to technology (at least computer technology) is Gibson's recent purchase of the once-renowned Baldwin Piano Company. Gibson has chosen to take even this famous music industry name, and make it a laughingstock. At this year's NAMM (National Association of Music Manufacturers) show they presented Baldwin pianos in gaudy, bright colors with graffiti-like drawings on them (for instance, one bright yellow grand had a desert scene painted on it with a Hummer riding across the desert floor in the the background - unbelievable!). I can see doing this to one piano, but the whole damn line? The instruments are laughable, and a blight on the once-reknowned Baldwin name.

    5)Gibson is run like a personal playpen and funhouse by current management, who is out of touch with market reality (and a few others); however, Gibson has good, dedicated people. For their sake I hope this technology cathes on.

    6)Other companies will be coming forward with technologies like this, and others. Let's wait and see if Gibson maintains its consistency in things having to do with technology, and screws this one up.

    Certainly, if this technology did catch on, *any* music instrument manufacturer licensing it would have to be *very* wary of Gibson's current management's penchant to sue fast and hard for any real or even (and especially) perceived violation of licensing or other agreements. This company is vulture-like when it comes to the law. Gibson is a great example of a company who is purchased by a management with a few crazy ideas and a lot of money. They come in, buy a well-established company with good products and dedicated peopl,e and make it a personal plaything. Gibson, and the music industry deserve better.

    first of all, IANA (I am not ancient) so my knowledge on this might be rusty. correct me if anybody knows better.

    Now, here are some reasons why tubes might sound better:

    first of all let's start with some tube basics: you heat a plate (cathod) and electrons jump off it. the electrons pass through a grid, and gets obsorbed at another plate (anode). You can vary the voltage on the grid and control how much eletrons pass - hence the amplifying.

    The difference between a tube amp and a FET amp is that tube amps have some insane amount of dynamic range that is very nice and linear. somethinge like 40V (or more, depending on the tube). It goes by the name "high voltage, low current."

    Now, for the same power, FETS can't touch this range because most fets don't operate at that high voltage level - and if you push it then it will saturate / turn off and you won't be linear anymore.

    So for the same power, FETS would go toward "low voltage, high current." This is cool and all, and theoretically if you stay within the linear region you are all good, right? wrong. All the EE books teaches you one thing that you never do in the real life - that is to assome a nice ground.

    ground is never nice - especially when there is a lot of current, ground tend to float here and there - which would give you crap and distortions that we all know and love. Of course, throughout the years engineers (hey we don't have a life, after all) figured some ways around it - but AFAIK all of these are either 1) very expensive, and 2) not completely effective (usually it's both). (btw, one of these is to make as much of the system digital as possible.)

    So... In the end, tube amps still reign. I heard that RCA made the best tubes, no confirmation on this, though.

    Just for the few who thought "well when we get lots of superconductors then finally FET amps will be better!" That's not correct either. Unfortunately superconductors we know of are only good for no resistance at DC, and the ground does not play nice because of AC concerns.

    So, there you have it. For the record I don't know any engineers who thought "oh yeah I can duplicate a tube response through other means," but they might have told their bosses shit like "I can make it damn close and you can't tell the difference" (which is usually a lie) so to keep their jobs.
