LED Guitar Pickups???

Hey guys,

I'm interested in putting LED lights in my guitars pickups. I've seen a few people do this on the net and gives a brilliant effect.

I know to put this all together on the guitar, the only problem i have is making a circuit for the LED's. I know there are instructables on how to wire LED's but none show any circuit with a switch.

I have all the equipment needed for this, eg. LED's, resisitor, 9V battery, toggle switch, wire etc.

So basically i'm asking whether someone would be kind enough to show me how to wire 2 series circuits which both consist of 4 LED's which connect back to a switch and a standard 9V battery connector.
And if possible, close up pictures would be very helpful.

For an idea of what i am on about here is a video of someone who has already done it, but i didn't find his instructions helpful at all.

Any help would be much appreciated.

Thanks Dan

I just bought some humbucker backlights from this bloke...

Yeah, I know I'm commenting on an old thread, but in case others want to see an answer to this, I've just written up how I acheived flashing LEDs via the guitar pickup wiring as a sound following circuit.

Let me know what you think.

that would be simple just wire the leds the long lead to + and short to ground one after another then take the long lead+ from one side of the circuit and and the short or- lead from the other side and sodder on wires tand feed them into the other pickup area (there should already be a hole that connects them...) and do the same thing but this time take the wires and feed them through the hole on the last pickup that goes to the elctrical area of the guitar (on the back that usually has a panel with a few screws that hold it in place...) and take the - wire and solder it directly into the 9v battery holders - wire and take your toggle switch and take the + lead from you LEDs and solder onto the left prong/middle prong of the switch and solder the + from the battery holder the the other prong usually the left prong... connect your battery screw in the back panel, reattach your pickups and flick on the switch!
i thik that would be so kool to mea it wicked !!!!

LED lights will work great underneath these: http://www.q-tuner.com

This twinkler is more advanced and pretty cool as it responds to the notes. His website is in Korean though.

I'm not a LED expert but maybe you could just gut out one of those bicycle warning flasher lights and embed that in your axe.

thanks for the reply. not quite sure about the flashing though. i remember reading on a forum about LED lights around a guitar body and many people said that and LED light that flashes can cause interference whilst playing. apparently every time it flashes the LED gives off alpha rays or something that cause the interference. but it's fine when an LED is constantly on as it will only produce a single ray once turned on (something on the lines of that, can't really remember it well).
Hmmm. An LED blinking in response to your playing "attack" shouldn't cause any interference to a guitar amp. The circuit would be switching at audio frequencies, not at RF and an LED doesn't emit anything other than light (in a very narrow bandwidth.)

After all, you're amplifying the same signal with 50 or 100 watt amps at those same frequencies; enough power to rattle your neighbor's windows. And the only interference is the usual audio feedback loop inherent to all audio amplfication. WAY less power to drive the LEDs.

But a poorly designed preamp circuit could probably produce some RF. And a low-impedance input would really "load" a standard guitar pickup, and that would muck with the signal.

So something hi-impedance (like a MOSFET) would be a good first stage. Even a hiZ CMOS logic chip could be used, ala Craig Anderton's Tube Amp Fuzz. Maybe fed to another transistor, or a LM386 to drive the LEDs... Add some roll-off caps to tame any high frequency noise, and it should work.

'Course, I'm just musing; maybe that's more than you care to tackle...
. Then all you need is a battery, a resistor, and an LED(s). The resistor will depend on what battery you use and the type/number of LEDs. Add a switch, if you want.
. Noahw has a great intro to LEDs. Even has links to info on calc'ing resistor value.
