Not real clear what you mean, but in every case I can think of, the answer would be no, with nothing for your trouble but grief and tears before bedtime.
To make an led light up with your playing, youd need an active circuit with at least one transistor, other components and a battery. I do not recomend this to you, unless you want to get into serious electronics.

I don't think the circuit has enough current to power LED's, my idea would be to have a seperate circuit, with a battery, a switch (maybe a push-pull?) and some LED's in series.

if it's just for lighting purpose only, u just make a simple circuit like a flashlight. put the battery somewhere inside ur guitar, add an on/off switch, and a resistor to make ur LED's voltage match the battery. Mind you, it doesn't have to be 9v.
But if u want the LEDs to be some kind of VU meter, then u get an active onboard preamp and "tap" a bit of its output to a VU circuit.
I really inexperienced in these parts, though.. I'm not an expert in electronics.
.. how's ur Digitech rp80, btw ?

This thread reminded me of an idea that I had a while back, but I was not smart enough to figure out if it could work.
When I was getting confused with all of the switching option available in a HH equiped axe I thought it would be great to put in some multi-colored LED's to indicate which coils of which pups were being used, and if possible show different colors for series, parallel, in/out of phase.
Sorry for getting off topic, maybe. I'll repost as a new thread if anyone would like to have further discussion.

Crunchypotato - I am very sorry to say that the circuit that you posted would not work - nice drawing though. Here are some of the reasons: - As far as I am aware, LEDS are not available in the low voltages you describe. Normally they need a forward voltage of in excess of 1.5V
- Wether it is possible to achieve a voltage boost or not with that design I dont know, but we cannot boost the power/energy available from a passive circuit. Boosting voltage by resonant effects cuts down on the current that can be produced. Its conservation of energy. A rough calc shows that the power available from a pickup is probably around a 100x too small to make an LED light effectively.
- Even if all of that was not true, drawing power out of the pup like that would wreck the sound of the pickup.
If however, someone builds it and it does work - let me know. I will try to get a refund on my engineering degree!. John

John John, forget about that refund. you only get your money back when you don't get what you paid for. from everything you've written on the boards, we can tell you've gotten everything you paid for and then some! you and i have, and probably will continue to have, slightly differing opinions on minor details. but it is obvious your knowledge IS soundly based in fact and reality. ______________________________________________________________________________________ ...If you decide to test it, the circuit components are very cheap. You will need: 1 - LED of .2V 1 - LED of .1V 1 - LED of .05V 1 - LED of .025V ..... other than travelling to an alternate universe, does any one know where a person could actually purchase such LEDs? Unklmickey P.S. please don't think, that getting LEDs that would illuminate at such low voltages would even come close to being the only problem with this idea.

JohnH (or his alias 'TheNewGuy' - Joey) "Objection; assumes facts not in evidence." -- Executive Asst. D.A. Ben Stone (Michael Moriarty) It looks like the earlier reference to Kirchoff's Laws got deleted. I was wondering if that was about Kirchoff's Current Law, "the algebraic sum of the current meeting at any point in a circuit is zero." (Also called Kirchhoff's first law, Kirchhoff's point rule, Kirchhoff's junction rule, and Kirchhoff's first rule.) Or would it be Kirchoff's Voltage Law (also called Kirchhoff's second law, Kirchhoff's loop rule, and Kirchhoff's second rule): "in travelling round any closed mesh (section) of a network (circuit), the algebraic sum of the emfs (voltages) acting in the mesh is equal to the algebraic sum of the IR voltage drops for the individual resistance in the mesh." So I wondered if it might be one of these: - A hot solid, liquid or gas, under high pressure, gives off a continuous spectrum.
- A hot gas under low pressure produces a bright-line or emission line spectrum.
- A dark line or absorption line spectrum is seen when a source of a continuous spectrum is viewed behind a cool gas under pressure.
I love Google. Even if I didn't know how to spell Kirchoff, it probably would have found all that stuff for me.

I'm ready and waiting. As soon as you can do, call Fender, they will be glad to know that the TBX don't works. War?i don't consider debate on the merits of an untested pipe-dream to be a war. evidently, from this, and the way you ran away the first time i tried to give you some advice, you apparently do! get over it!i've tried to refrain from responding to your posts, because i hoped that given enough space, the parts of your posts that were bogus would be exposed by other members. or by your own arrogance. mostly that was how things worked out. i'm certain JohnH could easily debunk this on his own. i took the bait, now it makes me look like a "bully". oh, well such is life. my only regret is that i couldn't resist the overwhelming desire on this thread, to point out the fact that the "very cheap" components in your theoretical design don't exist. (in fact elements and compounds with low enough activation energy to make them, don't exist, at this time, in this universe). kind of a waste of time for someone who might be gullible enough to try to build it. i have always been ready to admit my mistakes. anyone who has read all my posts, will know that. it only makes a person better (and more credible) to do so. try it sometime, if you can. i don't need to use high technical skills to explain the other problems with driving the LEDs directly from the pickups. it should be obvious that since there is no current in LEDs until the voltage exceeds the threshold voltage, they would cause some serious distortion of the signal when they do begin to conduct. i don't recall any disclaimer of this in your post. i won't even bother to do a "complete explanation" as i will be traveling again soon, and have higher priorities for the limited time i have available. but if you are around next week, i'll do some more "myth-busting". unklmickey p.s. i think Fender already knows the pickup driven LEDs in their TBX don't work. oh wait, that's right, they don't have any.

JohnH (or his alias 'TheNewGuy' - Joey) seems to be old enough to take charge of his own faults Just to let you know that I dont use any aliases. This thread has become quite amusing, but not in the way that I look for on GN2. I think we have put up enough info on the problems of the passive LED lights idea, and I dont plan on adding further to it. Crunchypotato - My previous post was simply a response to your question as to whether the circuit would work - nothing personal in what I wrote. My view is that it will not, but if you think it might work, why don't you try it? - then let us know. John EDIT Ive just noticed that several of Crunchies posts including the circuit, are now deleted. Nothing more to be said then.

R.H.
exaltation for keeping inexperienced modders safe from mods founded in bad science, and cute tongue-in-cheek humor. (just one for both though, not one for each.)
i was going to try to goad him into a real, live debate next week and see if we could "turn him from the dark-side". but i wonder if there was anything more than the smoke and mirrors of "harmonic distortion generated subharmonics" to that guy.
i kinda wonder about this karma thing, but i think i'll take that to a new thread

hehehe We had some fun when I was designing my sustainer with the idea of putting lights in it...I actually did at one point One guy had the idea of having Under lights like some pimped out car...(or some computers)...hehehe Anyway...check out some cheapo shops see if there aren't some little LED things about that you could destroy use for the purpose. It's often a good cheap source of LED's, I found a pen that changed colors with three LED's and a little circuit in it that was pretty cool. Cost half the price of one blue LED and worked off a little watch sized battery (included)! OH...and, if you are really keen, the circuit I use for my DIY sustainer puts out enough power to drive an LED. So they light up when you play and go off when you stop. Mind you, a bit of a waste and possibly not very effective at a distance, but it does work

Just a thought from the 60's - it was fairly common for people to have what was called a "light organ" that would flash red/green/yellow lights depending on volume and frequency. There must still be low voltage variant of that around somewhere, but I guarantee any lighting circuit will have to have it's own power source (batteries). Maybe hollowbody archtops were originally invented just to give us room to stuff our projects into (hoho).
(forgot to mention - the organ was triggered by your stereo through a small microphone).

Yeah...the colour organ is still available!!! I found this mini sound triggered LED version as a beginners kit that could be rigged up I'm sure... www.apogeekits.com/color_organ_light_kit.htmThere is a link to the old three chanell mains disco version too. This kind of kit is fairly commonly available and if connected to the guitar's output instead of the mike, should "light when played". I am sure that I have seen an ultra miniture version made into cases for mobile phones. It lights up when it rings...perhaps something like this could be used and it must run from the tiniest battery! As i say, when it was brought up elsewhere with the sustainer project there was actually quite a bit of interest in the Look. I could imagine there being a market of underlit pickups if anyone had the cahonjes to make them...perhaps an active set to justify the power on board. Anyway...notice I have not mentioned the war!! lol!

- 2 - lights that are driven directly from the guitar signal with NO active devices or batteries added.
- 3 - lights that are driven from the guitar signal by an active device that is battery powered.
- 4 - lights that are battery powered, and indicate pickups, coils, phase selection
- 5 - other (be specific)
it DO make a difference. unk

okay,
in that case the answer is:
NO it won't cause any extra noise.
the hard part is having extra poles on the phase switches and/or selector switch(es) to operate the lights.
with the extra poles, the lights and the guitar signal can be electrically isolated from one another.
without the extra poles, DON"T EVEN THINK ABOUT IT! some bright guy might come up with a way to try it, but you'll hear echoes of JohnH's remarks about "grief and tears before bedtime".
