Self-Tuning Electric Guitar 389
avirrey writes "The Technology Review has an interesting article on a Gibson Self-Tuning Guitar. Purist argue that you shouldn't need a guitar that self-tunes. Others argue that this will allow an artist to change tuning with one 'favorite' guitar, instead of having to swap out between songs." Ok I know what I think- freakin' sweet. Only technology will guarantee my sucking on the electric will at least be reasonably in-tune suckiness. Dear Gibson, Slashdot really needs to review your guitar. We'll need several review units and we lost your return address.

I thought about designing a self-tuning instrument once, but for piano, where the tuning process is a lot more painful. It would consist of basically a high speed camera and a strobe light that could be tuned to any frequency. For each piano pitch, it would hit the string, start the strobe, and compare the position on consecutive beats like a strobotuner, adjusting until it wasn't moving. Either that or just use a much faster high speed camera and skip the strobe light. The point is that by using optics instead of resonance, you could accurately discern an individual string's fundamental frequency without the need to stop down the remaining strings. Kind of what they did with piezo pickups, but a heck of a lot closer together. :-)
The whole thing could be built into a block that snapped down onto the three pins on a given model of piano and took advantage of the fact that there's more than one of them so that it wouldn't have to mount to anything else. With the single bass strings, you'd have to tune them by hand, but they're the easy strings.
Never built it. Never cared enough, never had time, never thought it would sell, etc.

Somewhat dissonant, maybe.
Not good, maybe.
But it takes a concerted effort to play painfully bad.

I don't think it would, unless all the alternate tunings are very similar to each other.
Getting the best sound out of a guitar using a specific tuning is not only a function of the tension on each string, but also the gauge and wrap of the strings. Take a guitar in normal EADGBE with medium-gauge strings and tune the bottom string down a step to D, and it'll still sound pretty close to ideal; but tune everything down a fourth to BEADF#B, and the sound will be thin and lifeless. You'll need to switch to heavier strings to play with that dropped tuning.
Besides which, half of the fun of a Steve Vai show is to check out all the different guitar models he has. There's his standard Jem, and there's the one with the brilliant blue LEDs inlaid into the fret markers, and there's the enormous heart-shaped guitar with three necks...

Real musical instruments are made of real materials like wood, metal, or nylon. As temperature and humidity change, the shape and flexibility of the parts are going to change, and the parts that are held by friction may also move. And the accoustics of the places you're playing will all be different, and the people you're playing with will have different skills and different instruments, and of course if people are singing their voices aren't super-consistent even if they can carry a tune, and sometimes your fingers or mind are more flexible than other times. And if you move your instrument around it'll also be affected by that. So go with the flow, listen to the sounds around you and adapt. (Oh, and bring an electronic tuner - they really do help unless you're one of those people with really good ears who can do it all with a tuning fork.)
I recently opened my baritone uke bag and found that the thing had exploded - must have overheated in the car or something, because the strings had pulled the bridge off the body. That's a bit more extreme than the usual environmental changes in instruments, but it's reasonably large and I'd bought it for $20 on eBay. Glued the bridge back on, and it's sounding a little dull but the strings may need a bit of time to readjust.
If you don't like all this analog behaviour, get yourself an electronic instrument. Or go with something semi-digital, like a horn with valves. The brass'll still change a bit with temperature, and your wind may vary with humidity as well as tiredness, and a small-mouthpiece instrument like a French horn is a lot less forgiving than a baritone horn or tuba. Or get yourself a slide trombone, where you're always going to have to move your the slide to the right distance to get just the right pitch...

The good thing about the Gibson is that you only pull on the knob when you have strummed the open strings, so the guitar knows that no notes are being bent... it knows what the pitches should be when you strum open strings, so it has no problem tuning it to those pitches.
Your idea could be implemented if, like on the Gibson, there were a button to let the guitar know it was in "tuning mode." When the button was pressed, the guitar would listen to see how out of tune it was, then when the button was released, the pitch-correction computer inside could change the pitch of each string by exactly the right amount to bring the guitar's output into tune, although the strings themselves would still be out of tune, and you could still bend them all you want without having the pitch "snap" to the next note like a vocal that has been auto-tuned.

Well, if this Gibson guitar came in an SG model...it WOULD be handy for doing some Sabbath, since Iommi does most of this stuff with the guitar tuned down. Less tension helps for his missing fingertips, and also is what contributed to making their 'dark' sound....
Strange, if Tony hadn't had that accident....BS might not have found their trademark 'sound' or tone.....
